  You should look at the nlme and lme4 packages to start with.  The former
is the subject of a 2000 book by Pinheiro and Bates, the latter is the
subject of a book draft (rather technical and incomplete at the moment,
but a good starting point) by Bates at <http://lme4.r-forge.r-project.org/book/>.
More specific questions (once you have read a bit) can be directed to
the r-sig-mixed-models mailing list.
