[R-SIG-Mac] packages failed to load - Now fixed

[Simon Urbanek]

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
