R help - Oct 2007 - How can i perform Fisher Exact Test for such data in R?

Dear all,

I am sorry, but this not exact a R question.It's a statistic one.
Suppose I have two vectors PA and PB, which are both consist of no-redundant
nature numbers. PA and PB have overlaps.GA and GB are drawn from PA and PB,
respectively.So GA and GB may have overlaps.
The question is whether GA and GB have significant overlap.Someone told me
Fisher Exact Test in R can do this.

Thanks in advance.
