Yes, we made it a requirement because many people tend to forget
about it. Maybe, in the next release, we will make it so that if it
is indeed a factor variable, you don't have to type it. For now,
please type as.factor().
Thanks,

Hmm, does not make sense that as.factor(y) needs to be called
nevertheless y is already a factor.
