[R] Installing packages into updated R

[Gabor Grothendieck]

In

  http://cran.r-project.org/contrib/extra/batchfiles/batchfiles_0.2-5.zip

are two Windows XP batch files:

  movedir.bat
  copydir.bat

which will move the packages (which is much faster and suitable
if you don't need the old version of R any more) or copy the packages (which
takes longer but preserves the old version).
