Subject: Remove term from formula for predict.lm
Hi,
probably just a quick question: can I somehow change the formula used with predict? E.g., the regression was run on "y ~ u + v + w" but for the prediction the term v should be removed from the formula contained in the regression object and only "y ~ u + w" be used.
I could use model.matrix etc. to do the predictions but it would be very helpful to know a simpler way.
Thanks so much,
Werner
