The standard advice is to use a separate library for packages you install.
R '2.60' is a long way off, so I am unable to predict what the advice will
be if it ever comes out.
Currently you can do
tmp <- installed.packages()
inst <- as.vector(tmp[is.na(tmp[,"Priority"]), 1])
in the old version to get a list of packages you installed. Then in the
If you have created a personal or site library, the latter will use that
for installation: next time around all you need to do is to copy that
library to the new version and issue
