[Bioc-sig-seq] IRange overlap percentage

[Kunbin Qu]

Hi,

I have some IRanges like the followings. I would like to find out the
overlap of x and y, and also the actual overlap percentage to each when
they overlap. For the following case, IRanges 3 in x overlaps with
IRanges 2 in y from 8 -9. Is there a function to call to give me the
overlap% for x and y, which are 2/3 = 67% for x, 2/4 = 50% for y? thanks
a lot!
