How can I install and use parallel R versions? In the install process, 
there is step 2 where I can see the suggestion of executing

pkgutil --forget org.r-project.R.x86_64.fw.pkg

Question: When, and in which directory, has this to be done? At all, if 
I want multiple versions (release and patched)

The paragraph
4.3 Multiple versions
is not clear enough for me
