[S] Newbie question: Extracting rows of a matrix with positive

This is a very very basic question. We tried several things and looked up
online help and the programmers manual but could not locate anything

I want to extract all the rows of a matrix X that have positive elements in
it. For example if X is:

0, 1,-1

then I want to extract only lines 2 and 3.

Thanks for any suggestions. (By the way I am curious as to where in the
programmers manuals issues like this are covered).
