How To Install R on Ubuntu 20.04 [Quickstart]

Logged into your Ubuntu 20.04 server as a sudo non-root user, add the relevant GPG key.

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9

sudo add-apt-repository 'deb https://cloud.r-project.org/bin/linux/ubuntu focal-cran40/'

If you’re not using 20.04, find the relevant repository from the R Project Ubuntu list, named for each release.

sudo apt update

sudo apt install r-base

Start R’s interactive shell as root.

sudo -i R

You should receive output similar to the following:

Output

This confirms that we’ve successfully installed R and entered its interactive shell.
