Dear list,
I have a vector (array, table row, whatever is best) of frequency values for categories (or bins), and I need to find the median category. Trivial to do by hand, but I was wondering if there is a means to do it in R in an elegant way.

The obvious medioan(vector) returns the median frequency for the binns, and that is not what I want. i.e,:

cat1 1
cat2 10
cat3 100

cat4 1000
cat5 10000

I want it to return cat5, instead of cat3.

Thanks a lot
