This link was useful to me, as I am new to R. (Win2000, R-2.5.0)
What I have been doing is using a file compare utility (Beyond
Compare in my case) to move files in the old "library" directory to
the new one, if the files are missing in the new one. Then I perform
an update.packages command.
This procedure appears to work without problem.
It would seem much preferable to have all packages saved in an
installation-independent directory, instead of a "library" directory
under R's installation directory. Then, of course, no update would be
I can't find how this option is settable in R, other than a direct
argument to library() or install.package().
How does one shift the R default libraries location to a particular directory?
