I am using R to teach, and here are a couple of things that I thought
would work didn't work.
1. I noticed the utility data(***,package=***) recently and like it
very much, but unless I type in the whole word "package" I'll get an
error in 1.4.0. For example, data(cats,package=MASS) works fine but
2. drop1 doesn't seem to be as smart as before. In the sequence
below, drop1 didn't produce what I expected it to produce.
The following sequence however works.
