Problem with lme4 use and installation
Nothing's wrong. It just means that the package or one of its dependencies, has its own xtabs function, which "hides" the default xtabs function, since it comes first in the search path. So when you next write xtabs(...), it is this new xtabs that is being loaded. If you want to call the original xtabs, you can still do it I think with stats::xtabs(...). This is a warning, not an error. It warns you that something you perhaps did not expect has just happened. Haris Skiadas Department of Mathematics and Computer Science Hanover College
