The development version of a package will contain a sneak peek of new functions and patches but may not be as stable or as bug free as the CRAN version. install_github is especially useful because many R developers provide development versions of their packages on GitHub. These work similar to install.packages, but they search new locations for R packages. devtools provides functions like install_github, install_gitorious, install_bitbucket, and install_url.

The devtools R package makes it easy to install packages from locations other than the CRAN website. This is because R automatically downloads a set of useful packages when you first install R. You may notice many packages that you donвЂ™t remember installing. Library() also shows the path to your actual R library, which is the folder that contains your R packages. To see which packages you currently have in your R library, run: library() After that, a copy of the package will live in your R library. You only have to install each package once. The next time you begin an R session, youвЂ™ll have to reload the package with library if you want to use it, but you wonвЂ™t have to reinstall it. Library will make all of the packageвЂ™s functions, data sets, and help files available to you until you close your current R session. (This is not true for the install.packages command).

For example, to install the ggplot2, reshape2, and dplyr packages, run: install.packages( c( 'ggplot2', 'reshape2', 'dplyr')) You can install multiple packages at once by linking their names with RвЂ™s concatenate function, c. This doesnвЂ™t eliminate every bug inside a package, but it does mean that you can trust a package on CRAN to run in the current version of R on your OS. CRAN tests each R package before publishing it.

Anyone can write an R package and disseminate it as they like however, almost all R packages are published through the CRAN website.

R can access the package here in future R sessions without reinstalling it. When R finds the package, it will download it into a libraries folder on your computer. This will search for the specified package in the collection of packages hosted on the CRAN site. Open R and type the following into the command line: install.packages( '') The easiest way to install an R package is with the install.packages R function.
