  Let me also point out that you will save a bit of time if you can
provide a *reproducible* example (see
e.g. http://tinyurl.com/reproducible-000 ), and full context, when you
post to r-sig-mixed-models .  Looking at your SAS and R code, nothing
jumps out as odd, so you will probably have to post more details in
order to get an answer ...
  Data sets don't always attach properly, using dput() is best if
you can.
