Dear Larry, That's odd: The only lmer of which I'm aware is a function in the lme4 package, and it creates objects of class "mer," I believe. What this has to do with the Rcmdr package is beyond me, since the Rcmdr doesn't depend upon lme4, but, on the other hand, shouldn't conflict with it. I don't think that you've mentioned it, but I assume that you're using the current version (1.4-7) of the Rcmdr package.
Is it possible that you have a saved and damaged workspace that's being loaded at the start of your R session? If so, remove the saved workspace (I'm afraid that I don't know where that lives on a Mac, but I suppose that getwd() would show you).
