[R] Installing different R versions

[Wolfgang Raffelsberger]

check out the official document
*R Installation and Administration*
from https://cran.r-project.org/manuals.html
There you'll find how to define a specific path for each installation.

(Since a number of years I administrate multiple versions of R at different
platforms, of course including Linux)
