Hi!

Let's say I have vector x with positive integer values ranging from 1 to 
N. I need to obtain another vector y of size N where y[i] contains the 
number of times value i occurs in x. It is in a sense similar to hist() 
(with appropriate number of breaks) or table() with numeric "factors".

Currenlty I use a custom function for that, but thought maybe there is a 
more "direct" way in R.

Thanks!
