    How to Install a Package in R (example included)

    For the most part, this template may be used to install a package in R: install.packages(″package name″).This section will show you how to install the readxl package solely for the purpose of demonstration.This utility is used to import Excel files into the R programming language.

    • The same procedures that will be discussed may be used to install additional packages in R as well as those that will be discussed here.

    Steps to Install a Package in R

    Step 1: Launch R

    To get started, you’ll need to open the R programming language. You’ll then see the R Console, which looks like this: >

    Step 2: Type the command to install the package

    Now, in order to install your package, you’ll need to follow the steps outlined below: install.packages(″package name″) For example, in order to install the readxl package, you may use the following command in the R Console: install.packages(″readxl″) To proceed with the installation, once you have finished typing the command, hit ENTER to confirm your selection.

    Step 3: Select a Mirror for the installation

    Finally, choose a Mirror for the installation as the final stage in the process. Alternatively, you might select a mirror that is more convenient for you in terms of location.

    Step 4: Start using the package installed

    You’ll need to load the package you just loaded into the R Editor before you can begin using it. For example, to load the readxl package, you’ll need to execute the following command: library (″readxl″) Consider the following scenario: you wish to import an Excel file into R (in this case, the Excel file is named ‘Products’). The following information is contained within the Excel document:

    product price
    Laptop 1200
    Tablet 350
    Printer 150
    Keyboard 100

    Allow us to suppose that the file is located in the following location for demonstration purposes: C:\\Users\\Ron\\Desktop\\Products.xlsx As a result, this is the code to import the Excel document: library(″readxl″) read excel(″C:\\Users\\Ron\\Desktop\\Products.xlsx″) For this reason, you must modify the path to match the location of the Excel file on your computer (don’t forget to include a double backslash within the path name to avoid any issues).When you run the code in R, you’ll obtain the following table, which corresponds to the data provided in the Excel file: Price of products: 1 Laptop 1200 $ 2 Tablet 350 $ 3 Printer 150 $ 4 Keyboard 100 $

    Library Path Management

    First and foremost, it should be noted that SCF personnel will generally install a R package on a machine upon request.You may, however, install programs directly within your home directory if you so like.As a result, if you want a package fast or on an ad hoc basis, or if the package is very specialized, you may want to consider installing it locally.

    • When you request operations involving libraries, R looks for them in a predefined set of directories by default.
    • As a result, when calling procedures such as install.packages(), the first path is utilized by default, resulting in messages such as the following: It was not possible to create the directory /server/linux/lib/R/site-library/00LOCK because permission was refused by the operating system.
    • error: unable to lock directory ‘/server linux lib R site library’ for editing purposes.
    • Fortunately, R includes a variety of ways for customizing the library route that may be customized to meet the needs of virtually any user.

    Temporarily changing the library path

    If you want to make a one-time change to R’s concept of your library path, you may do so by passing the lib= parameter to install.packages.Assume you have a directory called MyRlibs in your home directory that you want to use.When you run the command install.packages(‘caTools’,lib=’/MyRlibs’) in your local directory, the provided package will be installed.

    • It must be accessed by the library’s lib.loc= parameter, which is as follows: library(‘caTools’,lib=’~/MyRlibs’) One issue with this technique is that if a local library calls the library() function, the library() function will not know to search the local library as well.

    Changing the library path for a session

    The.libPaths() method takes a character vector containing the names of the libraries that are to be utilized as a search path as an argument.It should be noted that folders that are currently in the search route will not be automatically retained.In addition, because the.libPaths() function returns the current search path when it is used with no parameters, an invocation such as.libPaths(c(‘/MyRlibs’,.libPaths()) will place your local directory at or near the start of the search path.

    • Thus, the installation of packages will be handled by the install.packages() method; similarly, calls to the library() function will locate libraries in your local directory without the need for further parameters.

    Permanently changing the library path

    It is possible to override the R LIBS environment variable (in a shell starting file, for example) in order to personalize your library path.The R LIBS environment variable is set by the script that runs R.This variable should be set to a colon-separated list of directories to be searched for in the search path.

    • Due to the fact that it is always set inside a R session, the simplest approach to obtain a starting point for it is to use Sys.getenv(): > Sys.getenv(‘R LIBS’) ″/usr/local/linux/lib/R/site-library:/usr/local/linux/lib/R/site-library:/usr/lib/R/site-library:/usr/lib/R/library″You might then build a

    How to Install and Include an R Package

    We receive a large number of inquiries regarding the use of R libraries.The most often asked question is ″Can I use all of the R libraries in your notebooks/consoles?″ The most common response is ″Yes.″ Yes!You can make use of any of the libraries that have been uploaded to the R package repository, even those that are proprietary (CRAN).

    • Start up your notebook or console by typing the following:

    1. Install

    Install.packages(“ggplot2”) If the package hasn’t previously been installed, this will complete the installation.

    2. Include

    Library(ggplot2) This will call/include the library into your session as a result of your action.

    3. Use

    Ggplot(data=iris,aes(x=Sepal.Length,y=Petal.Length))+geom point() Remember that when installing packages, you must use quote marks inside the install.packages(″″) method, but you do not need to use quote marks when incorporating packages using the library ().Once libraries have been installed, you will not be required to reinstall them.You may just call them with the library() function and then utilize them as you see fit.

    Quick-R: R Packages

    The R package is a collection of R functions, data, and executable code that is organized in a predefined manner.The library is the directory in which packages are kept and is located in the package installation directory.R comes with a standard set of packages that are easy to use.

    • Others are accessible for download and installation on a computer or device.
    • Once they have been installed, they must be loaded into the session in order to be utilized.
    • libPaths() returns the location of the library library() returns a list of all the packages that have been installed search() returns a list of the packages that are presently loaded

    Adding Packages

    By incorporating other software programs, you may broaden the scope of the studies you do. CRAN maintains a comprehensive record of the packages that have been donated. Take the following steps:

    1. Obtain and install a package (this is something you only need to do once)
    2. The library(package) command is used to load the package into the current session, which allows it to be used. This must be done once for each session, unless you have configured your environment to load it automatically at the start of each session.

    On MS Windows:

    1. Select Install Packages from the Packages drop-down menu
    2. and
    3. Select a CRAN Mirror from the drop-down menu. (For example, Norway)
    4. Select a travel package. (for example, a boot)
    5. Then, to make it available for usage, call the library(package) method. (For example, library(boot))

    About Packages in R

    The R package is a collection of R functions, data, and executable code that is organized in a predefined manner.A package offers you access to a collection of commands that are not accessible in the standard R set of functions when you install it.The library is the directory in which packages are kept and is located in the package installation directory.

    • R comes with a standard set of packages that are easy to use.
    • Others are accessible for download and installation on a computer or device.
    • Once they have been installed, they must be loaded into the session in order to be utilized.

    Installing Packages in R

    In order to install a package, you must first determine where you may obtain the package.The majority of well-known packages are accessible via ″CRAN,″ which stands for the Comprehensive R Archive Network.Packages are downloaded from specified CRAN ″mirrors,″″ which are locations where the packages have been kept (assuming that a binary, or set of installation files, is available for your operating system).

    • The options() window will appear if you haven’t specified a preferred CRAN mirror in your configuration.
    • A menu will appear asking you to select a location from which you’d want to install your packages.
    • Installing a package from CRAN is accomplished through the use of the install.packages command ().
    • You only need to install packages the first time you use R.
    • After that, you are done (or after updating to a new version).

    Install the ggplot2 package on your system.install.packages(″ggplot2″) **R’s Insider Tip:** To install any package, you may simply put the following into the command line of R.Once a package has been installed, it is not necessary to reinstall it while using the current version of R!

    Use a Package

    Using R, you need to ″call″ a package into the current session of the program once it has been installed (essentially, the functions have been downloaded into your computer).In essence, this is the equivalent of saying, ″Hey R, I’m going to be utilizing these functions right now, please get them ready.″ This is something that needs to be done every time you start a new R session, so it should be towards the beginning of the script.When you wish to call a package, you should use the library keyword (PackageNameHere).

    • You may also see some individuals using require() – while this works in most circumstances, it does operate in a slightly different manner, and it is recommended that you use library rather than require() ().
    • the package library must be loaded (ggplot2)

    What Packages are Installed Now?

    If you wish to utilize a package but aren’t sure whether or not you’ve already installed it, you may do a check!Installed can be used in code, if desired.packages().

    • Installed packages should be checked for.
    • packages() If you are working with RStudio, you should also have a look at the Packages page.
    • A check mark will appear next to any currently loaded and ready-to-use packages in the list of those that are currently installed and ready to use.
    • This page also allows you to do package updates and installations.
    • In addition to calling a package from here by ticking the box, I would not advocate doing so because contacting a package is not part of your script, and if you execute the script again, this might cause confusion.

    Updating Packages

    Packages are occasionally updated by the users who originally produced them.When updating packages, it is possible that changes will be made to both the package and the way your code executes.** If you have a large amount of code that relies on a package, you should exercise caution while upgrading packages since some functionality may alter or disappear.

    • Alternately, go ahead and update outdated packages to ensure that everything is up to date.
    • You may use the old.packages() function in your code to determine whether packages are out of date.
    • The function update.packages() will do an interactive update of all packages in the known libraries.
    • If you haven’t done this in a while, it may take a little longer!
    • Use the ask = FALSE parameter to force everything to be updated without the need for user participation.

    Using install.packages() once more is the best technique to update a single package if you just want to make a single change to it.list all packages for which an update is available old.packages() update all packages that are currently available update.packages() does an update without prompting the user for permission or clarification.update.packages(ask = FALSE) is a method that updates packages.just a single package has to be updated install.packages() should be used instead of install.packages() (″plotly″) In RStudio, you may manage packages by selecting Tools -> Install Packages from the menu bar.

    The NuGet Package Manager Console enables you to utilize NuGet PowerShell commands to locate, install, remove, and update NuGet packages through the use of NuGet PowerShell commands.When the Package Manager UI does not give a mechanism to accomplish an action, it is required to use the console to complete the task.See Using the nuget.exe CLI in the console for further information on how to use nuget.exe CLI commands in the console.

    • On Windows, the console is included as part of Visual Studio.
    • There are no Visual Studio for Mac or Visual Studio Code editions that include this add-on.
    • Important While the instructions provided in this section apply specifically to the Package Manager Console in Visual Studio, they differ from the Package Management module commands that are accessible in a more generic PowerShell context.
    • Precise commands that are only accessible in one environment are not available in the other, and commands with the same name but different arguments may also differ in their specific parameters.
    • It is necessary to use the Package Management Console in Visual Studio in order to make use of the commands and parameters mentioned in this article.

    Find and install a package

    In the case of packages, for example, identifying and installing them may be accomplished in three simple steps:

    1. Open the project/solution in Visual Studio and launch the Package Manager Console by selecting Tools > NuGet Package Manager > Package Manager Console from the menu bar.
    2. Locate the package that you wish to install. If you are already aware of this, you can go to step 3. Packages containing the term ″elmah″ will be found. Package elmah may be found by searching for it on the internet.
    3. Run the following installation command: Install the Elmah package to the project named MyProject by specifying the package name. Using the command Install-Package Elmah -ProjectName MyProject, you may create a new project.

    Important The NuGet CLI provides access to all of the same actions that are available via the NuGet console.Console commands, on the other hand, function inside the context of Visual Studio and a stored project/solution, and as a result, they frequently achieve more than their CLI equivalents.When a package is installed through the console, a reference to the project is added; however, this is not the case when the package is installed with the CLI command.

    • As a result, developers working in Visual Studio often choose to use the console rather than the command line interface.
    • Tip It is necessary to have an open solution in Visual Studio with an identifiable path name before doing many console tasks.
    • If you have an unsaved solution, or if you have no solution, you will be able to identify the error ″The solution has not been opened or saved.
    • Please confirm that you have a solution open and saved on your computer.″ This means that the console was unable to detect the location of the solution directory.
    • Attempting to save an unfinished solution, or generating and saving a new solution if you don’t already have one open, should resolve the problem.

    Opening the console and console controls

    1. Using the Tools > NuGet Package Manager > Package Manager Console command in Visual Studio, you may access the package manager console. You may organize and position the console in any way you like in Visual Studio (see Customize window layouts in Visual Studio for more information).
    2. As a default, console commands work on a certain package source and project, which may be selected in the control at the top of the window:
    3. Selecting a different package source and/or project from the drop-down menu affects the settings for the commands that follow. Most commands provide the -Source and -ProjectName arguments, which allow you to override these parameters without affecting the defaults.
    4. Selecting the gear icon will allow you to manage package sources. Using this shortcut, you may quickly access the Tools > Options > NuGet Package Manager > Package Sources dialog box, which is detailed in further detail on the Package Manager UI page. Additionally, the control to the right of the project selector clears the contents of the console:
    5. The rightmost button terminates a command that has been running for a long time. As an example, the command Get-Package -ListAvailable -PageSize 500 shows the top 500 packages available on the default source (such as nuget.org), which may take several minutes to complete.

    Install a package

    • Add the Elmah package to the default project, which can be found in the project selection on the console’s main screen. Install-Package Elmah Add the Elmah package to a project named UtilitiesLib that is not the default project for the Elmah package. Install-Package UtilitiesLib is a project named Elmah. See Install-Package for further information. It is possible to install packages through the console, which follows the same procedure as that described in the section What occurs when a package is installed, with the following additions: The Console shows the licensing conditions that apply in its window, with the user’s implicit agreement. If you do not agree with the conditions of the agreement, you should remove the item as soon as possible.
    • Also, a reference to the package is added to the project file and shows in Solution Explorer under the References node
    • however, you must save the project in order to view the changes in the project file immediately
    • additionally,

    Uninstall a package

    • Removes the Elmah package from the current project’s default configuration. Uninstall-Package Elmah This command uninstalls the Elmah package and all of its dependencies that are no longer needed. Uninstall-Package Elmah -RemoveDependencies is a command line option. Uninstalls the Elmah package, regardless of whether or not another package is dependent on it. Package Elmah must be uninstalled using the force option. See Uninstall-Package for further information. If you need to locate an identifier for a package, you may use Get-Package to examine all of the packages that are presently installed in the default project. When you uninstall a software, the following activities are carried out: Deletes any references to the package from the project’s source code (and whatever management format is in use). References are no longer displayed in the Solution Explorer window. (It is possible that you may need to rebuild the project in order to see it removed from the Bin folder.)
    • Reverses any modifications that were made to app.config or web.config during the installation of the package.
    • Once previously installed dependencies have been removed, the package that relied on them is no longer required by any other packages.

    Use Get-Package instead of Get-Package with Visual Studio 2013 and older versions.

    Availability of the console

    Starting with Visual Studio 2017, NuGet and the NuGet Package Manager are automatically installed when you select any.NET-related workloads; however, you can also install it separately by selecting Individual components > Code tools > NuGet package manager from the Visual Studio installer’s Advanced options.You may also check Tools > Extensions and Updates and look for the NuGet Package Manager extension if you are using Visual Studio 2015 or earlier and are missing the NuGet Package Manager functionality.It is possible to download the extension straight from the Visual Studio extensions installer if you are unable to use it in Visual Studio.

    • The Package Manager Console is not currently accessible with Visual Studio for Mac, which is a shame.
    • The NuGet CLI, on the other hand, provides access to the corresponding commands.
    • Visual Studio for Mac does have a graphical user interface (GUI) for managing NuGet packages.
    • See Including a NuGet package in your project is a simple process.
    • Visual Studio Code does not contain the Package Manager Console, which can be found here.

    Extend the Package Manager Console

    How to Manually Install Python Packages

    ActiveState has significant roots in open source, and as a founding member of the Python Foundation, the company gives back to the Python community in a variety of ways.We provide the simplicity, security, and support that your organization requires, while remaining compatible with the open source Python distribution that you are already familiar with.Download ActiveState Python to get started, or get in touch with us if you have any questions about implementing ActiveState Python in your company.

    • Nowadays, the vast majority of Python packages are created to be compatible with Python’s pip package management.
    • It is necessary to manually install Python packages if you are using a package that is not compatible with the pip package management system.
    • Here’s how to do it.

    Python Installation Checklist

    Before installing any package, you should always make sure that you have a working Python installation in place that has all of the essential files for installing packages. To do this, follow the instructions in the Installation Requirements.

    Packages That Cannot be Installed with Pip

    The following are the preliminary steps to be taken:

    1. Download the package and unzip it into a temporary directory on your computer
    2. If the package comes with its own set of installation instructions, those should be followed as closely as possible. Otherwise, the most often used approach for manually installing a package is to use the setup.py script.

    Installing Python Packages with Setup.py

    The following steps should be followed to install a package that contains a setup.py file: Open a command or terminal window and type the following:

    1. Cd into the root directory of the computer where setup.py is found
    2. Enter the command: python setup.py install.

    Setup.py Build Environment

    Packages installed using setup.py have build requirements that developers must follow in order for them to function properly. Some of the prerequisites, on the other hand, are optional.

    Examples

    In order to ensure that setuptools is up to date, make sure that the following is done:

    Setuptools -upgrade setuptools pip install -upgrade setuptools Install requires keyword arguments should be included in setup. Python installation requirements are specified using the setuptools setup.py keyword py. install requires in setuptools setup.py. As an illustration:

    Installation requirements are specified using the term install requires= Setup requires all of the package build criteria to be met completely. PyPA (Python Packaging Authority) provides a sample project that demonstrates how to install Python on a computer.

    Sample Project

    Sample Project is a template package that includes a setup.py file that may be used to manually install a program.The file is annotated with comments that may be used to customize the script as well as for the broader package development environment.The setuptools package is used in the sample project, which is described as follows: ″A setuptools based setup module.″ setup.py is the script that is used to construct packages that are created with setuptools.

    Setup.py Example (Non-Annotated)

    Import setuptools as fh using open(″README.md″, ″r″): long description = fh.read() setuptools.setuptools.setuptools.setuptools.setuptools.setuptools.setuptools.setuptools.setuptools.setuptools.setuptools.setuptools.setuptools.setuptools.setuptools.setuptools (name=″″, description=″″) Substitute your username for the following values: version=″1.0.0,″ author″,″ author email=″″, description=″,″ long description=long description, long description content type=″text/markdown″, url=″=3.6′,)

    How ActiveState Can Help

    • ActiveState is a single cross-platform toolchain for contemporary Python package management that is built on top of Python 3. It may be used to replace the complicated and time-consuming in-house solutions that are constructed from a variety of package managers, environment management tools, and other solutions. Using the ActiveState Platform, developers are able to perform the following tasks: automated building of packages from source code, including linking C libraries, without the need for a local build environment
    • automated building of packages from source code
    • automated building of packages from source code.
    • Resolution of dependencies in an automated manner (or advice on how to manually resolve conflicts), guaranteeing that your environment always comprises a set of known excellent dependencies that operate well together
    • Management of a single source of truth for your environment that can be deployed with a single command to all development and CI/CD environments, guaranteeing constant reproducibility
    • central management of a single source of truth for your environment
    • Installation of virtual Python environments on Windows or Linux systems without the need for any previous configuration
    • Having the capacity to automatically identify, patch, and rebuild insecure environments, hence improving security and drastically lowering the time and effort required to resolve CVEs
    • Visually observing which versions of which packages have been cleared for usage, hence removing the element of surprise from the development process

    To access the majority of the Platform’s capabilities via the command line, users may make use of the ActiveState Platform’s command-line interface (CLI), known as the State Tool, which functions as a universal package manager for Python and offers access to most of the Platform’s functionality.

    How to install packages on R + screenshots

    (You may report a problem with the content on this page by clicking here.) You’d want to post your stuff on R-bloggers, right? If you have a blog, go to this page; if you don’t, go to this page. Do not be alarmed, the screenshots are available! (To view the original instruction, please visit this page.)

    Part 1-Getting the Package onto Your Computer

    1. Choose your chosen way of launching R (desktop icon, Start Menu entry in the dock, etc.)
    2. Packages may be installed by selecting ″Install package(s)″ from the top menu.
    3. Choose a mirror that is the most convenient for you in terms of location
    4. You now have the option of selecting the packages you want to install. Installing numerous packages is as simple as clicking on each one while holding down the CTRL key (or the cloverleaf-looking key) on your keyboard. For the time being, simply highlight ″ggplot2′′.
    5. Another greater-than sign (″>″) will display on your computer screen to indicate that the package has been downloaded to your machine.

    Part 2-Loading the Package into R

    1. Type “library(ggplot2)” and then click the Enter/Return key
    2. you’re finished
    3. thank you.

    If you are using a computer, you will only need to complete Part 1 once. From now on, you will only need to complete Part 2 each time you close and reopen the R program. Make use of this strategy once you’ve become more familiar with the copy and paste process in general. It is significantly more expedient than Method 1.

    Part 1-Getting the Package onto Your Computer

    1. Type “install.packages(“gplots”)” and then press the Enter/Return key to complete the sentence
    2. If you have previously loaded a package from a server into your R session, R will install the package for you without your intervention. If you do not, R will ask you to select a mirror on its own initiative. Again, find one that is close by unless you want to sit and watch a loading bar slowly inch its way towards completion.

    Part 2-Loading the Package into R

    1. Type ″library(gplots)″ into the search box and hit the Enter/Return key
    2. Everything has been completed.
    3. Because it needs to install additional packages necessary by gplots, R will generate a significant amount of additional output.

    Once again, you will only need to complete Part 1 on your computer a single time. From now on, you will only need to complete Part 2 each time you close and reopen the R program.

    Starting R

    If R has been correctly installed, starting the program by simply typing R on the command line of a terminal should be sufficient. In Windows, the application is often stated as the action that is executed when a user clicks on a certain icon. Alternatively, you may use this approach on a *NIX system that is equipped with a window manager such as KDE.

    Where does it start?

    R begins in the current directory by default, unless the command associated with it specifies a different location.In order to incorporate the working directory specification into the R starting file, it is convenient to include the following line: Shift; cd $1;; go to the R script at roughly line 120, immediately before the line that starts with:)*.Using a command line like: > R -s /home/jim/R/analyses allows you to launch R using a command line like: Unless it is the command that is executed by one of the icons on the command line, this may not appear to be of much value as an input to a command line.

    • If you have many R icons, they may all start up in various folders, allowing you to handle your information a little more efficiently.
    • Another method, as discussed in The R Script, is to incorporate the directory change in a script file that is being executed.

    Stopping it

    R includes a function q() that will terminate the current session and prompt you to choose whether or not to add the objects and commands from the current session to the.RData and.Rhistory files, which are located in the current directory.If you choose not to participate, everything was in there before to the current session will stay in place.In addition, the a.Last() method may be used to automate your exit from the program.

    Installing and Using R Packages – Easy Guides – Wiki

    • In our earlier articles, we released I how-to guidelines for installing and starting R/RStudio, ii) an introduction to R programming, and iii) how-to guides for seeking assistance in R. We’ll go through what a R package is, how to install and utilize R packages, and how to create your own R packages.

    An R package is an extension of the R programming language that contains data sets and specialized functions that are used to answer specific questions.When R is installed, it includes standard (or base) packages that include the fundamental functions and data sets, as well as standard statistical and graphical tools, that are required for it to function.CRAN, Bioconductor, and GitHub repositories all include thousands of more R packages that may be downloaded and installed as part of the R development process.

    • After installation, you must first load the package in order to be able to use the functionalities contained inside the package.
    • Packages can be downloaded and installed from CRAN (for general packages), Bioconductor (for biology-related programs), or Github (for open-source packages) (developing versions of packages).

    Install a package from CRAN

    Installing a package from CRAN is accomplished through the usage of the install.packages() method.The following is the syntax: install.packages(″package name″) For example, to install the package named readr, put the following into your browser: install.packages(″readr″) Please keep in mind that every time you install a R package, R may prompt you to choose a CRAN mirror location (or server).Specify a server that is close to your location, and R will establish a connection to that server in order to download and install the package files.

    • Installing numerous packages at the same time is also feasible, as seen in the following examples: install.packages(c(″readr″, ″ggplot2″)) is a function that executes when a package is installed.

    Install a package from Bioconductor

    Bioconductor is a collection of tools that may be used to analyze biological data. Installing the R/Bioconductor package limma, which is specialized to the analysis of genomic data, is what we’re aiming for in the following R code. If you want to install a package from Bioconductor, follow these steps: (″ biocLite ″) as the source (″limma″)

    Install a package from Github

    In addition to R packages, GitHub is a valuable repository for many types of software development and data analysis work.It makes it simple to distribute your bundle.You may learn more about GitHub by visiting this page: Hadley Wickham is the author of Git and GitHub.

    • In order to install a package from GitHub, the R package devtools (created by Hadley Wickham) should be used.
    • In order to proceed, you must first install devtools on your computer if you do not already have them installed.
    • If you want to use survminer, the following R code will automatically install the current version of the R package produced by A.
    • Kassambara (install.packages(″devtools″) devtools:install github(″kazsambara/survminer″)

    View the list of installed packages

    To get a list of the packages that have already been installed on your machine, enter the following command: installed.packages () It should be noted that in RStudio, the list of installed packages may be found in the lower right window under the Packages tab (see image below) (see the image below).

    Folder containing installed packages

    • R packages are installed in a directory named library, which stands for library directory. The R function.libPaths() may be used to obtain the path to a library’s resources. libPaths() ″/Library/Frameworks/R.framework/Versions/3.2/Resources/library″ ″/Library/Frameworks/R.framework/Versions/3.2/Resources/library″ It is necessary to load a R package using the function library in order to use a specific function that is present in that package (). In the following R code, we wish to import a file (″ into R by utilizing the R package readr, which was previously installed in the previous phase of the tutorial. When importing a tab separated.txt file, the following method can be used: read tsv() Import my data library into the program (″readr″) my data = read tsv(″my data″) View the first six rows and the first six columns using the following syntax: my data my data’s identifier Long-jump distance of 100m Shot.put High.jump400m 1SEBRLE 11.047.5814.832.07 49.81 1SEBRLE 11.047.5814.832.07 2CLAY 10.767.4014.261.86 49.37 3KARPOV 11.027.3014.772.04 49.37 4CLAY 10.767.4014.261.86 49.37 BERNARD 11.027.2314.251.92 48.93 5YURKOV 11.347.0915.192.10 50.42 BERNARD 11.027.2314.251.92 48.93 6 WARNINGS 11.117.6014.311.98 48.68 11.117.6014.311.98 During a R session, the search() function may be used to display a list of the packages that have been loaded (or attached): search() ″.

To uninstall a R package that has been installed, call the function remove.packages() as follows: remove.packages(″package name″) If you wish to update all of the R packages that are currently installed, type the following: update.packages() If you want to update certain installed packages, such as readr and ggplot2, follow these steps: update.packages(oldPkgs = c(″readr″, ″ggplot2″)) is a function that updates the packages in a database. install.packages(“package name”): Install a package
    • library(″package name″): Load and use a package
    • library(″package name″): Load and use a package
    • Detach(″package name″, unload = TRUE): detach(″package name″, unload = TRUE): Remove a package from the system using remove.packages(″package name″): Removing a previously installed package from your PC is accomplished by using update.packages(oldPkgs = ″package name″): Update a package’s contents

    Loading and/or Installing Packages Programmatically

    (You may report a problem with the content on this page by clicking here.) You’d want to post your stuff on R-bloggers, right?If you have a blog, go to this page; if you don’t, go to this page.The typical technique of loading packages in R can occasionally result in circumstances where multiple lines of code are required merely to load a single package, which is not ideal.These lines might create issues if the packages are not installed, and they can also be difficult to manage, which is especially true throughout the deployment process.The good news is that there is a technique to develop a function in R that will load our packages for us automatically.In this post, I’ll guide you through the process of conceptualizing and developing such a function.

    It is necessary to verify whether a package is already installed before writing a function that checks whether the package has already been loaded or installed, and then installs the package if it has not already been installed.Fortunately, this method accomplishes the task: If mypkg has been installed, then function(mypkg) is.element(mypkg, installed.packages()) will return true.The above code was derived from a message on the R mailing list, however I am not sure whether it is the source of the function.This method will check to see if a specific function name exists in the list of installed packages by using a string argument.

    We can get the list directly by using installed.packages(), and we can use the function by attempting is installed().We can also access the list indirectly by using installed.packages() (″foreach″).As soon as we understand how to determine if a package has been installed or not, we can go on to coding the function.At the present, we are confronted with two obstacles.

    A character vector of names is used to load a package, and the first problem is how to do it.The second topic is how to install a package using a programming language.Typically, the process of loading a package will look somewhat like this: library(MASS) As a fortunate side effect, the library function has a character.only option that allows us to specify the package name as a string.library(″MASS″,character.only=TRUE) The code above provides us with the capability we want in order to send the name of a package to a function as a string and have the package loaded into memory.Now we must figure out how to install packages, which may be accomplished through the use of the install.packages function: install.packages(″MASS″,repos=″ R will not ask us for the repository if we explicitly set it when the function is performed for the first time, as it would otherwise.

    • I used statlib for the sake of simplicity, but you are free to use any other repository you choose.
    • In this version, we have a method for testing if a package is installed, a method for installing the package, and a method for loading the package.
    • All we have to do now is put it all together using an if statement.
    • if(!is installed(package name)) install.packages(package name,repos=) if(!is installed(package name)) if(!is installed(package name)) ″package name, character.only=TRUE, quietly=TRUE, verbose=FALSE, library(package name, character.only=TRUE, quietly=TRUE, verbose=FALSE) The if statement above will check to see if a package has already been installed, and if it hasn’t, it will install it.
    • After that, it will begin loading the package.
    • However, if we want to send a character vector to the function and have it load numerous packages at the same time, we’ll need to wrap everything in a for loop.
    1. This will get us most of the way there.
    2. the function for(package name in package names) is equivalent to if(!is installed(package name)) and install.packages(package name,repos=) respectively ″library(package name,character.only=TRUE,quietly=TRUE,verbose=FALSE) library(package name,character.only=TRUE,quietly=TRUE,verbose=FALSE) This for loop will carry out the actions on the character vector package names that we need to complete our task.
    3. As a result, we can simply wrap everything into a single function that is run when a character vector named package names.load or install-function(package names) is supplied as an argument.

    for(package name in package names) if(!is installed(package name)) if(!is installed(package name)) install.packages(package name,repos=) is a function that installs packages ″lib(package name,character.only=TRUE,quietly=TRUE,verbose=FALSE) lib(package name,character.only=TRUE,quietly=TRUE,verbose=FALSE) We may invoke the function using the following syntax (in which the function names are substituted with your own): load or install(c(″foreach″,″MASS″,″doParallel″)) As a result, we have a method that can load or install packages as needed from a character vector, and we have completed our task.If the install.packages function or the library function fails to locate the supplied package name, this code will end with an error; however, you may correct this by using a try statement, which is an exercise that I will leave to you for the time being.

    Building and installing an R package

    You now have the basic materials necessary to create a straightforward R package.After that, you’ll have to put it together.A file named brocolors 0.1.tar.gz will be created, which you can either install (so that it can be loaded and used within R) or send to a friend to install.Typically, I do this from the command prompt (on my Mac).If you’re using Windows, you’ll want to make sure you have Rtools installed.

    Building an R package

    • Start by opening a terminal window.
    • Navigate to the directory that contains the package directory
    • and
    • Replace brocolors with the name of your package directory, which is ideally the same name as the name of your package, and then type
    • You’ll see anything along the lines of this. $ R CMD $ R CMD $ R CMD $ R CMD construct brocolors * attempting to locate the file ‘brocolors/DESCRIPTION’ OK Prepare the ‘brocolors’ in the following ways: * examining the meta-information for the DESCRIPTION. OK * examining source and make files for LF line ends * examining source and make files for empty or unnecessary directories establishing the default NAMESPACE file * constructing the brocolors 0.1.tar.gz archive And you should now have the brocolors 0.1.tar.gz file (or the equivalent for your package) in your possession.

    Installing an R package

    R CMD INSTALL brocolors 0.1.tar.gz is the command to use to install the package (at the command line). To check that it was successfully installed, run R and type library(brocolors) to verify whether it was successful. Then try out one of the functions. For my package, I’d experiment with brocolors() and plot crayons() ()

    Building and installing a package using devtools

    Even simpler than the methods described above is the usage of Hadley Wickham’s devtools package.The package may then be built and installed directly from within R.Start R from within your package directory (so that your package directory becomes R’s working directory), and then navigate to your package directory.Install the devtools by executing install.packages (inside R) on the console (devtools) After that, load the devtools package using the command Then, in order to assemble the package, write This will result in
