This tutorial explains how you can install GNU R and RStudio (libre version) on Ubuntu. This applies to the OS version 22.04 and later as well as the older ones. R is the software environment for statistical computing & graphics from The GNU Project, an alternative to the proprietary S language. On the other hand, RStudio is a graphical program that allows users to use R in convenience and more. A combination of both is a strong free/libre open source replacement to SPSS. Finally, this article is a companion to our Libre SPSS Alternatives. Now let's install them.
