Installing R 2.12.0 did not overwrite my old 2.11 folder in :
/Library/Frameworks/R.framework/Versions/2.11
RSwitch is able to launch (some) old versions, but I am not sure about
all. (I now have a collection going back to 2.7)

Hi,
What's the cleanest way to restore R 2.11.1 without clobbering R
2.12?
I know that pkgutil can be used to forget old receipts in order to
upgrade
to a higher version of R while retaining the lower one and then
Rswitch
can be used to choose the one to run. But, this didn't seem to work
in
the reverse direction, i.e., I have R 2.12 patched installed and I
tried
to install R 2.11.1 after running pkgutil. Rswitch did not record
that
R 2.11.1 had been installed and the GUI bombed out on startup (I
probably
have to install the R 2.11.1 GUI separately).
Do I have to uninstall R 2.12 before reinstalling R 2.11.1 and then do
use pkgutils, or is there a simpler way?
The reason for wanting to do this is that I need to process some
documents
using Sweave that use the cacheSweave package, which currently is not
working correctly with R 2.12, even though an update has been promised
imminently.
Thank you.
Ken
