R is a most widely used open-source programming language among statisticians and data miners to develop a statistical software, data analysis and more. It’s a free software environment for statistical computing, graphical and visual presentation by the R foundation.
In this tutorial we cover how to install and compile R on Ubuntu 20.04. Let’s start the tutorial.
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
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9
Output: Executing: /tmp/apt-key-gpghome.JC9K3gjUVy/gpg.1.sh --keyserver keyserver.ubuntu .com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9 gpg: key 51716619E084DAB9: public key "Michael Rutter
" impo rted gpg: Total number processed: 1 gpg: imported: 1
After adding trusted GPG key to your Ubuntu 20.04 server, then add the repository from R Ubuntu packages. Ubuntu 20.04 is known as Focal Fossa.
sudo add-apt-repository 'deb https://cloud.r-project.org/bin/linux/ubuntu focal-cran40/'
To Update the repository run the commands below:
sudo apt update
To install R on Ubuntu 20.04 run the commands below:
sudo apt install r-base
After installation of R check the version.
Output: R version 4.0.1 (2020-06-06) -- "See Things Now" 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.

Hooray we have successfully installed R on Ubuntu 20.04 server. Let start compiling R.
CRAN have more R packages you can find install it by install.packages(). For this tutorial we can install string package.
To open R run the following command:
To install and load the stringr package from CRAN execute the command below:
Create a simple task:
technologytu <- c("Technology", "Tutorials", "is", "the", "Best", "Blog", "for", "Learning")
Output:  10 9 2 3 4 4 3 8
