>From a user's point of view: - lme only accepts nested random effect; lmer handles crossed random effects - lme has a convenient methof of handling heteroscedasticity; lmer doesn't. - lme gives you p-values; lmer doesn't (there is explanation of why at https://stat.ethz.ch/pipermail/r-help/2006-May/094765.html which, I guess, should not be all that reassuring for lme users either) Steve Ellison ******************************************************************* This email and any attachments are confidential.
