st: Sorting/ranking Q from new user

["Eric VonDohlen" <evondohlen@san.rr.com>]

I have a continuous variable X, which I would like to:

(a) sort in ascending or descending order;
(b) rank the sorted X into some specified number of groups;
(c) report the mean of X (or some other statistic) by group.

Can anyone help?

Sorry for the elementary query.

Thanks in advance
