R is an open-source programming language. It’s specially used for statistical computing and data mining for developing statistical software and performing data analysis. This tutorial covers how to install R on CentOS 8 system.
Before you start installation on CentOS, ensure that:
- You are logged in with non-root user account with administrator privileges.
- Your system has at least 1GB of RAM.
Installing R on CentOS
By default R packages are not available in CentOS repositories. We will install it from the EPEL repositories.
sudo yum install epel-release
If EPEL repository not installed on your machine you then add it using below command:
It will prompt to accept the repository GPG key, type
y and hit
Once the repository added issue below command to install R:
sudo yum install R
You can verify the installation by running the following command which will print the R version:

R is installed successfully on your CentOS system, and you can start using it.
Install R Packages from CRAN
R is popular because of wide availability of packages through the Comprehensive R Archive Network (CRAN).
We are going to install a stringr package for an example, which provides fast, correct implementations of common string manipulations.
Start by opening the R console as root:
sudo -i R
It will show as below:
R version 3.6.3 (2020-02-29) -- "Holding the Windsock" Copyright (C) 2020 The R Foundation for Statistical Computing Platform: x86_64-pc-linux-gnu (64-bit) R is free software and comes with ABSOLUTELY NO WARRANTY.

Type 'demo()' for some demos, 'help()' for on-line help, or 'help.start()' for an HTML browser interface to help. Type 'q()' to quit R. >
stringr package just type:
It will show output as below:
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 that is closest to your location.
Installation will take some time and after completion load library using:
Let’s create a simple vector named
demo <- c("How", "to", "Install", "R", "on", "CentOS", "8")
Now run the below command to print the length of a string:
 3 2 7 1 2 6 1
If you want to install more packages you can find it at CRAN Packages.
