A complete list of contributed packages is available from CRAN. You can expand the types of analyses you do be adding other packages. Search() # see packages currently loaded Adding Packages Once installed, they have to be loaded into the session to be used. Others are available for download and installation. The directory where packages are stored is called the library. This may take a while.Packages are collections of R functions, data, and compiled code in a well-defined format. After making our selection, installation will begin. When prompted, we’ll select 1 for 0-Cloud, which will connect us to the Content Delivery Network (CDN) provided by RStudio, in order to get the geographically closest mirror. To make devtools available site-wide, we’ll enter R’s shell as root:įrom within the monitor, we’ll use the install.packages() function to install devtools from the official Comprehensive R Archive Network (CRAN). Step 2 - Installing the Devtools Packageĭevtools will enable us to install and build packages directly from GitHub, BitBucket, local files, as well as to install specific versions from CRAN. Once this is complete, we’re ready to proceed. 
sudo apt-get install build-essential libcurl4-gnutls-dev libxml2-dev libssl-dev.We’ll install devtools from the interactive shell, but before we do, we’ll need to install these system dependencies:
Step 1 - Installing System Dependencies for devtools How to Set Up R on Ubuntu 16.04 can help you.

In this tutorial, we’ll show you how to install devtools and use it to install a package directly from GitHub. R is easily extensible, and the community is known for continuously adding user-generated packages for specific areas of study, which makes it applicable to many fields. It is widely used for developing statistical software and performing data analysis. R is a popular open source programming language that specializes in statistical computing and graphics.
