By Andrie de Vries, Joris Meys. You install a package in R with the function — wait for it — install. So, to install the fortunes package, for example, you simply give the name of the package as a string to the install. The fortunes package contains a whole set of humorous and thought-provoking quotes from mailing lists and help sites.

You install the package like this:. R may ask you to specify a CRAN mirror. Because everyone in the whole world has to access the same servers, CRAN is mirrored on more than 80 registered servers, often located at universities. It tells you which directory called a library the package files are installed in, and it tells you whether the package was installed successfully. Granted, it does so in a rather technical way, but the word successfully tells you everything is okay.How to Manually Install Latex Packages with MikTex on Windows 10
After a while, you can end up with a collection of many packages. If R loaded all of them at the beginning of each session, that would take a lot of memory and time. So, before you can use a package, you have to load it into R by using the library function. The library is the directory where the packages are installed.
Never, ever call a package a library. Take a look at the following, and never forget it again:. You can use the fortune function without arguments to get a random selection of the fortune s available in the package.

Set Working Directory: This lesson assumes that you have set your working directory to the location of the downloaded and unzipped data subsets. An overview of setting the working directory in R can be found here.
If available, the code for challenge solutions is found in the downloadable R script of the entire lesson, available in the footer of each lesson page. Packages are collections of R functions, data, and compiled code in a well-defined format.
When you install a package it gives you access to a set of commands that are not available in the base R set of functions. The directory where packages are stored is called the library. R comes with a standard set of packages. Others are available for download and installation. Once installed, they have to be loaded into the session to be used.
To install a package you have to know where to get the package. Packages download from specific CRAN "mirrors"" where the packages are saved assuming that a binary, or set of installation files, is available for your operating system. If you have not set a preferred CRAN mirror in your optionsthen a menu will pop up asking you to choose a location from which you'd like to install your packages.
To install any package from CRAN, you use install. You only need to install packages the first time you use R or after updating to a new version. R Tip: You can just type this into the command line of R to install each package.
Once a package is installed, you don't have to install it again while using the version of R! Once a package is installed basically the functions are downloaded to your computeryou need to "call" the package into the current session of R. This is essentially like saying, "Hey R, I will be using these functions now, please have them ready to go". You have to do this ever time you start a new R session, so this should be at the top of your script.
When you want to call a package, use library PackageNameHere.
You may also see some people using require -- while that works in most cases, it does function slightly differently and best practice is to use library. If you want to use a package, but aren't sure if you've installed it before, you can check! In code you, can use installed. If you are using RStudio, you can also check out the Packages tab.
It will list all the currently installed packages and have a check mark next to them if they are currently loaded and ready to use. You can also update and install packages from this tab. While you can "call" a package from here too by checking the box I wouldn't recommend this as calling the package isn't in your script and you if you run the script again this could trip you up! Sometimes packages are updated by the users who created them. Updating packages can sometimes make changes to both the package and also to how your code runs.
This can take a while if you haven't done it recently!

If you only want to update a single package, the best way to do it is using install. Skip to main content. This tutorial provides the basics of installing and working with packages in R.
Challenge: Installing Packages Check to see if you can install the dplyr package or a package of interest to you. Check to see if the dplyr package is installed on your computer. If it is not installed, install the "dplyr" package in R. If installed, is it up to date?
Comments just came across this useful Submitted by Niels not verified on February, A fast, consistent tool for working with data frame like objects, both in memory and out of memory. You can learn more about them in vignette "dplyr". As well as these single-table verbs, dplyr also provides a variety of two-table verbs, which you can learn about in vignette "two-table".
That means as well as working with local data frames, you can also work with remote database tables, using exactly the same R code. If you are new to dplyr, the best place to start is the data import chapter in R for data science. If you encounter a clear bug, please file a minimal reproducible example on github.

For example, if you are usually working with data frames, probably you will have heard about dplyr or data. But imagine that you'd like to do some natural language processing of Korean texts, extract weather data from the web, or even estimate actual evapotranspiration using land surface energy balance models, R packages got you covered!
Recently, the official repository CRAN reached 10, packages published, and many more are publicly available through the internet. If you are a more experienced user, you can always learn something new like the name of the three packages I just mentioned in the previous paragraph.
In any case, welcome to this introduction to R packages and how to use them! A package is a suitable way to organize your own work and, if you want to, share it with others.
Typically, a package will include code not only R code! A repository is a place where packages are located so you can install them from it. Although you or your organization might have a local repository, typically they are online and accessible to everyone.
Three of the most popular repositories for R packages are:. How you can install a package will depend on where it is located. So, for publicly available packages, this means to what repository it belongs.
The most common way is to use the CRAN repository, then you just need the name of the package and use the command install. For example, the oldest package published in CRAN and still online and being updated is the vioplot package, from Daniel Adler. After running this, you will receive some messages on the screen. They will depend on what operating system you are using, the dependencies, and if the package was successfully installed. This indicates where your package is installed on your computer, and you can give a different folder location by using the lib parameter.
Here you receive information about the origin and size of the package. This will depend on the CRAN mirror you have selected. These are the messages of the installation itself, the source code, the help, some tests, and finally, a message that everything went well and the package was successfully installed. Depending on what platform you are, these messages can differ. The last piece of information is telling you where the original files from the package are located. They are not necessary for the use of the package, so they are usually copied to a temporary folder location.
Finally, to install more than a package at a time, just write them as a character vector in the first argument of the install. If you are using R through the RGui interface, you can do it by selecting it from the list which appears just after you use the install. On RStudio, the mirror is already selected by default.Tilde-expansion will be done on file paths. If this is missing, a listbox of available packages is presented where possible in an interactive R session.
Recycled as needed. If missing, defaults to the first element of. For more details on supported URL schemes see url. URL s of the contrib sections of the repositories. Use this argument if your repository mirror is incomplete, e. Overrides argument repos. Unused if a non- NULL available is supplied. Only supported if lib is of length one or missingso it is unambiguous where to install the dependent packages. If this is not the case it is ignored, with a warning.

TRUE means to use c "Depends", "Imports", "LinkingTo", "Suggests" for pkgs and c "Depends", "Imports", "LinkingTo" for added dependencies: this installs all the packages needed to run pkgstheir examples, tests and vignettes if the package author specified them correctly.
Used only for source installs. A character vector or a named list. If a character vector with no names is supplied, the elements are concatenated into a single string separated by a space and used as the value for the --configure-args flag in the call to R CMD INSTALL. If the character vector has names these are assumed to identify values for --configure-args for individual packages.
This allows one to specify settings for an entire collection of packages which will be used if any of those packages are to be installed. These settings can therefore be re-used and act as default settings. A named list can be used also to the same effect, and that allows multi-element character strings for each package which are concatenated to a single string to be used as the value for --configure-args.
Analogous to configure. This is sometimes used to perform additional operations at the end of the package installation in addition to removing intermediate files. Values greater than one are supported if the make command specified by Sys.
This can also be used on Windows to install just the DLL s from a binary package, e. Can also be a named list of character vectors to be used as additional options, with names the respective package names.
This is not passed to available. Alternatively, a character string giving the directory in which to save the outputs. Ignored when installing from local files. Arguments to be passed to download. This is the main function to install packages. It takes a vector of names and a destination library, downloads the packages from the repositories and installs them.
If the library is omitted it defaults to the first directory in.
If lib is omitted or is of length one and is not a group writable directory, in interactive use the code offers to create a personal library tree the first element of Sys. For installs from a repository an attempt is made to install the packages in an order that respects their dependencies. You are advised to run update. R packages are primarily distributed as source packages, but binary packages a packaging up of the installed package are also supported, and the type most commonly used on Windows and by the CRAN builds for macOS.
This function can install either type, either by downloading a file from a repository or from a local file. Possible values of type are currently "source""mac.

I am currently trying to run some R code on a computing cluster but cannot run the install. Since I am only using a few packages in my R code, I was hoping to avoid using the install. Unfortunately the people in charge of my cluster are not being helpful in setting this up so I'm forced to consider this alternative approach.
Ideally, I would like to download the packages files from CRAN to my computer, then upload these files to the cluster and install them using the appropriate commands in R. In addition, I would also like to make sure that the packages are installed to a location of my choice since I do not have the permission to "write" in the default R directory I believe that I can do this within R by using the.

The simplest way is to download the most recent R- x. On other systems you need to have the gzip program installed, when you can use. The pathname of the directory into which the sources are unpacked should not contain spaces, as most make programs and specifically GNU make do not expect spaces.
If you want the build to be usable by a group of users, set umask before unpacking so that the files will be readable by the target group e. Keep this setting of umask whilst building and installing.
If you use a fairly recent GNU version of tar and do this as a root account which on Windows includes accounts with administrator privileges you may see many warnings about changing ownership.

The Subversion repository does not contain the current sources for the recommended packages, which can be obtained by rsync or downloaded from CRAN. To use rsync to install the appropriate sources for the recommended packages, run.
A suitable incantation from the top level of the R sources using wget might be for the correct value of dir. See the FAQ for current details. These are installed in platform-specific ways, so for the rest of this chapter we consider only building from the sources.
Cross-building is not possible: installing R builds a minimal version of R and then runs many R scripts to complete the build. First review the essential and useful tools and libraries in Essential and useful other programs under a Unix-alikeand install those you want or need. Choose a directory to install the R tree R is not just a binary, but has additional data sets, help files, font metrics etc. Untar the source code.

Issue the following commands:. Users of Debian-based bit systems 4 may need. Failures are not necessarily problems as they might be caused by missing functionality, but you should look carefully at any reported discrepancies.
Some non-fatal errors are expected in locales that do not support Latin-1, in particular in true C locales and non-UTF-8 non-Western-European locales. R may indicate inadequate resource limits see Running R. Note that these checks are only run completely if the recommended packages are installed. You could also copy the man page R. If you want to install the complete R tree to, e. Note: you do not need to install R: you can run it from where it was built. This has the advantage of always keeping your source tree clean and is particularly recommended when you work with a version of R from Subversion.
