Dear CG, An addendum to my previous response: If you do decide to recompile the Rcmdr package to eliminate the dependency on nlme, as I suggested, you'll also have to edit the .onLoad() function in the package (which is in the file startup.R in the source package) to remove "nlme" from the vector of required packages.
