[R-SIG-Mac] keeping two patch level releases of the same minor release installed

[Gregory Jefferis]

Hello,

I use Rswitch in conjunction with CRAN installers to keep different minor releases series (e.g. 3.2.X vs 3.1.X) installed.

Now I find that I want to install 3.2.2 and 3.2.1 at the same time, so I tried

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

on install, but 3.2.1 disappears, presumably because the contents of /Library/Frameworks/R.framework/Versions/ looks like this:

3.1	3.2	Current

Can anyone suggest an easy way to keep and switch between the patch level releases?

With many thanks,

Greg.
