Look at help(sink). I have figured out how to fix up draw.tree to do
factor labels correctly and will be doing that in the next few days.
Meanwhile I discovered that rpart() provides factor labels in a much
more satisfactory way than tree() does. Because of this and because of
the additional information rpart provides about the tree building, I
recommend you switch to that.
