Isn’t MASS one of the default packages that come with R?  We’ve
previously added a package that is among the default packages, but I
don’t remember if that was a good decision.

Do you happen to know if this is considerably different from the
recommended and bundled package that comes with R?

This doesn’t need to be a full sentence.  It would be sufficient to
start with “Functions and datasets...”.

What does “to support the book” mean?  Could this be expressed more clearly?

Thanks!
