By default, R packages are available in the Ubuntu repositories, but we can’t find always the latest release of R packages. Find trusted external repository and install R on Ubuntu, we can install it by CRAN repository. Let’s begin the R installation.

To install the R on ubuntu 20.04 first we need to add the GPG key
