R is a fast growing open source programming language that specializes in statistical computing and graphical representation.
This programming language is supported by the R Foundation for Statistical Computing and is primarily used by statisticians and data miners to develop statistical software and perform data analysis.
This tutorial will teach you how to install R on Rocky Linux 8, CentOS 8 and AlmaLinux 8
Make sure you meet the following prerequisites before continuing with this tutorial:
- Your system has at least 1G RAM. Otherwise, you can create a swap file.
- You are logged in as a user with sudo privileges.
Install R on Rocky Linux 8 and CentOS 8
The R packages are not included in the Rocky Linux 8 and CentOS 8 core repository. We will install R from the EPEL repository :
To install R on Rocky Linux 8 or CentOS 8, follow these steps:
1) Enable EPEL and PowerTools repositories:
sudo dnf install epel-release sudo dnf config-manager --set-enabled PowerTools
2) Install R by typing:
sudo yum install R
R is a meta-package that contains all the required R components.
3) Verify the installation by printing the R version:
At the time of writing, the latest stable version of R is version
R version 3.6.2 (2019-12-12) -- "Dark and Stormy Night" Copyright (C) 2019 The R Foundation for Statistical Computing Platform: x86_64-redhat-linux-gnu (64-bit) R is free software and comes with ABSOLUTELY NO WARRANTY.

4) Install the libraries and tools used by the R package:
sudo yum install make gcc gcc-c++ libcurl-devel libxml2-devel openssl-devel texlive-*
At this point, you have successfully installed your Rocky Linux 8 and CentOS R system and can start using it.
Install Package R from CRAN
One of the main reasons why R is so popular is the variety of packages available through the Comprehensive R Archive Network (CRAN).
For demonstration purposes, we will install a package named
stringr, which provides a fast and correct implementation of general string manipulation.
When started as root, the packages will be installed globally and available to all users of the system. If you start R without sudo, a private library will be set up for your users.
Start by opening the R console as root:
sudo -i R

All of the following commands are executed in the R console.
stringrby running the following command:
You will be asked to select a CRAN mirror link:
Installing package into ‘/usr/lib64/R/library’ (as ‘lib’ is unspecified) --- Please select a CRAN mirror for use in this session --- Secure CRAN mirrors
Select the mirror closest to your location.
The installation will take some time and once done, load the library by typing:
Next, create a simple character vector named
tutorial <- c("Cara", "Install", "R", "di", "CentOS", "8")
Run the following function which will print the length of each string:
 4 7 1 2 6 1
