There is a documented bug in R 2.15.2 and R 2.15.3. The developers
decided not to fix this with an update, but it has been fixed with R
3.0.0 (perhaps also with R 3.0.1, which I have not tried myself). So,
upgrading R should take care of this problem.

Dear Simon,
I respectfully disagree with you, when you say that it is NOT a bug. Empty

something like k=4, it cannot happen, so it must be a bug. Which one is
your case?
