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!
