Hi Seth,

thanks for your reply!
verbose=FALSE or TRUE doesn't change anything
and example(mas5) give the same error...
I re-install the last R-patched from source nothing changed, I  
install in despair R binary and I am still having the same problem.

Can I re-install update.default() method manually?

I am working on a apple intel MBP with 10.4.9.
any suggestion welcome,
