How To Install R on Ubuntu 20.04 [Quickstart]
An open-source programming language, R specializes in statistical computing and graphics. In this tutorial, we will install R on an Ubuntu 20.04 server.
For a more detailed version of this tutorial, with more thorough explanations of each step, please refer to How To Install R on Ubuntu 20.04.
Step 1 — Adding GPG Key
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
Step 2 — Adding the R Repository
- 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.
Step 3 — Updating Package Lists
- sudo apt update
Step 4 — Installing R
- sudo apt install r-base
Step 5 — Testing the Installation
Start R’s interactive shell as root.
- sudo -i R
You should receive output similar to the following:
