[R-sig-ME] nlme random effect

[Douglas Bates]

Generally it is best to send questions like this to the
R-SIG-Mixed-Models at R-project.org mailing list (see instructions at
https://stat.ethz.ch/mailman/listinfo/r-sig-mixed-models).  Many of
those who read that list can reply and often much faster than I am
able to.

I think we would need a bit more information to be able to respond.
