2.6 What's the best way to upgrade?

That's a matter of taste.  For most people the best thing to do is to
uninstall R (see the previous Q), install the new version, copy any
installed packages to the library folder in the new installation, run
`update.packages()' in the new R (`Update packages from CRAN' from the
Packages menu, if you prefer) and then delete anything left of the old
installation.  Different versions of R are quite deliberately
in parallel folders so you can keep old versions around if you wish.
