Step 1 : Install R 

First, you need to install the epel repo for centos and rhel using below command. Make sure yum works on your machine.

sudo yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

Install R software using below command

sudo yum install R -y

You are done with one part that is R installation, next you need to install R studio.



Step 2: Install R studio


You can find the latest version of R studio for Centos and RHEL 7 from here
Make sure wget is installed on your machine, you need to download the package first and then install it using yum command as given below
