That's good - often people say "crash" when all they have seen is a
"stop" from R.

Nicely up to date...

Oh don't do that! You're not asking how to do basic statistics, you
are trying to do it yourself and getting a crash. Fair question for
starters...

Yes! This looks like a bug in that package function, a bit of
investigation seems to blame it on when you have repeated values in
the vectors:

[1] 0.025

Functions shouldn't crash like this - so time for you to email the maintainer:

The function disappears into C code, but I suspect its dividing by
zero somewhere...
