Have you tried lme in the nlme package? Pinheiro and Bates (2000)
Mixed-Effects Models in S and S-Plus (Springer) describes how to do that
-- though perhaps not in exactly your terms. If you have studied the
book and still can't see how to do it, please submit another post --
after reading the posting guide!
"www.R-project.org/posting-guide.html".
Please include a simple, self-contained, reproducible example showing
something that you tried to help illustrate what you don't understand.
From a one-line question, it is difficult for anyone to guess what you
might not know.
hope this helps.
