[R] to run an older version of R on my machine

[Alfredo Cortell]

Hi Bogdan,

The way I do this is the following: I have different R versions installed,
and then I downloaded and use Rswitch to change between versions. You just
open it, select the version you want, and R will open in that version
directly. It works with R and Rstudio in a MacOS HighSierra, although I
have read that it doesn't work in every platform. I don't know about
ubuntu. I would advise you to try it anyhow. Good luck with that!

All the best,

Alfredo
