Hi there, I have the following data:
1 1
2 1
3 1
4 1
5 1
6 2
7 2
8 1
9 1
10 3
11 3
12 3
13 4
14 4
15 4
16 4
etc
where column 1 is userid and column 2 is whether it is unique or not (thus, users 13-16 are duplicates, 10-12 are duplicates, and 6 and 7 are duplicates. I need an output variable labeling each user as a unique value, so something like this:
1 1 1
2 1 2
3 1 3
4 1 4
5 1 5
6 2 6
7 2 6
8 1 7
9 1 8
10 3 9
11 3 9
12 3 9
13 4 10
14 4 10
15 4 10
16 4 10
Thanks!
That is a strange structure. Also what are the NAMES of those variables?
data want ;
set have ;
by var2 notsorted ;
var3 + (first.var2 or var2=1);
run;

I agree it's strange, why I needed to find a way out of it. And you have provided just that! Cheers!
