Of course, but I would not recommend it. A factor is a vector of integers with
an attribute containing the labels that those integers correspond to. You seem
to be asking for a factor that has lost the definitions part. But hey,
newvector <- as.integer(factor(oldvector)) should get you what you asked for
one column at a time.
