predict.mlm() does not appear to work properly with newdata specified
(it seems to ignore newdata in my applications). I suggest replacing
X <- model.matrix(object, newdata)
with something like
X <- model.matrix(delete.response(terms(object)), newdata)
(see the corresponding section in predict.lm()).
