How to get R up and running in Fedora Linux

sudo dnf install R

After that you can run R in the terminal. If you want an environment to work in you can use RStudio. I use Emacs and ESS. Everything works nice up until the point you want to install a package — say for example car. It wont work (out of the box). You need to install an additional program. In the terminal:

sudo dnf install libcurl-devel 

libcurl is a client-side URL transfer library that you need to install packages in R.

It is also a good idea to install:

sudo dnf install NLopt

NLopt is a library for nonlinear optimization, callable from R.
