Same as then.
glmmPQL in MASS (approximate, but not a bad approximation)
glmm in GLMMGibbs (needs careful tuning in the binomial case, but
has worked for me).
There is a section and a couple of worked examples in MASS4. The
best method there uses R/S+C code which is not yet available to public
release, but we expect it to be within 6 months.
