I never noticed that... However, q("no") should work. I also forgot that q()
doesn't use match.arg() (did it ever?).

Yes, so changing working directory to somewhere non-writable might cause it.
That's the more likely scenario, I agree.
(I'm not completely ruling out .Last(). A colleague of mine uses a .Last() to

workspace to the hard drive, the unsuspecting next teacher using R on that
machine may find himself unable to quit.)
