This is due to long-staning issue in methods internals, which are

involved because loading Matrix shadows base::mean with Matrix::mean.

A work-around has been in place in R_devel for some time; a proper fix

may come at some point in the future. So if your real code doesn't

need the moficied mean from Matrix you can use base::mean; otherwise

you will have to use an R-devel snapshot.
