Well, that's a bit convoluted way (I really don't see the point of that
"script") - if you want to re-install packages across R versions (not the topic
of this thread!) it is far easier than that and I posted it here just a few
days ago:
# for packages from user location:
install.packages(row.names(installed.packages("~/Library/R/2.12/library")))
# for packages from system location:
install.packages(row.names(installed.packages("/Library/Frameworks/R.framework/Versions/2.12/Resources/library")))
but as I said, the Package Manager gives you the latter without the need to
type anything ...
Cheers,
Simon
