Well, you could simply use everything from the old library and just apply

update.packages(checkBuilt=TRUE)

in order to get the packages updated for the new release.

Hello,



                I am going to install the new version of R 2.14.1. After the
installation, I want to copy my installed packages to the new library. But
since over time I forgot which ones I installed I want to get a list of all
the packages I installed among the packages installed initially by the
R-installer. Is this possible?
