Hi all - (this is posted to r-help and R-SIG-MAC)
OSX 10.3.7, R 2.0.1, lme4/Matrix/latticeExtra latest, fresh install of
R. MASS loaded (or not).
I am getting an error message for the print() and summary() commands
with all lme models I try and run in lme4 (GLMM's work fine). Using
the example from the lme help, summary and print produce the following
errors, despite the model being fit, as indicated by VarCorr() and
examination of str(fm). Any ideas?
(I can't reproduce this on a windows95 install of 2.0.1, so I am
guessing it may be a mac thing at the moment? This happens with the
binary or the source installation of lme4.)
Cheers
andrew

It looks as if you have loaded lme4 and nlme at the same time and you their methods will conflict.
