[R] Problem with lme4 use and installation

[Charilaos Skiadas]

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.
