st: display identifiers accounting for duplicate obs

Hello all,
I can't come up with this solution despite spending quite some thought and time. The problem in hand sounds fairly straigh forward
I have a dataset like following
hits
1
2
3
4
4
5
6
6
and I want to generate variable rank. Notice, if there were no duplicate obs, i would have said
gsort -hits
gen rank=_n and rank column would have given the ranks of the obs. That is what i want.
However, there are some duplicate obs and i tried doing
gsort -hits
gen rank=cond(hits[_n-1]==hits[_n], _n-1, _n) which would give me
hits rank
6 1
6 1
5 3
4 4
4 4
3 6
2 7
1 8 and that is not what I want.
I looked at commands like generate, duplicates and I didn't see much relevant to my problem.
Could someone give me a lead where to look at or which command should I dig in ? Thanks a lot.
Tashi
