[R-SIG-Mac] [R] Upgrading R means I lose my packages

[William Revelle]

This is actually an R-sig-mac question so I am responding there.


In general, if you want to install a new version without losing the 
previous packages,  using the finder, go to Library/Receipts and 
remove the R.app and R.Gui receipts.  Then install the new version. 
That will keep the previous packages.  This is not mysterious, this 
is R.


Thanks to Simon et al. for the upgrade.

Bill
