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

which I execute in the terminal literally.

But this procedure does not prevent the new version from eliminating the 
old version.

What am I missing?
