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 mainly used by statisticians and data miners to develop statistical software and perform data analysis.
This tutorial will teach you how to install R on CentOS 8.

Install Package R from CRAN
One of the main reasons for R’s popularity is the great variety of packages available through the R’s comprehensive archive network (CRAN).
For demo purposes, we will be installing a package named
stringr, Which provides fast and correct implementation of general chain processing.
When started as root, the packages will be installed globally and available to all system users. If you start R without sudo, it will create a private library for users.
Start by opening R console as root:
sudo -i R

Next, create a simple letter vector called
tutorial <- c("Cara", "Install", "R", "di", "CentOS", "8")
Run the following function that will print the length of each string:
 4 7 1 2 6 1
You can find more R packages in CRAN package by name supplied and installed with
