Hi all,
I would like assign a sequential order for my data. I have id dose variables. like below
ID DOSE
1 20
1 20
1 17
1 17
1 15
1 15
I want like below
ID DOSE SEQ
1 20 0
1 20 0
1 17 1
1 17 1
1 15 2
1 15 2
Can you please help me with this.
Thanks,
Adi
One way:
data want;
set have;
by id dose notsorted;
if first.id then seq=0;
else if first.dose then seq + 1;
run;
I don't believe you. Prove me wrong by posting the log from your job where it doesn't work.

Don't be silly.

input id dose;
datalines;
1 20
1 20
1 17
1 17
1 15
1 15
;
data want;
set have;
by id dose notsorted;
if first.id then seq=0;
else if first.dose then seq + 1;
run;
proc print data=want noobs;
run;
Result:
id dose seq 1 20 0 1 20 0 1 17 1 1 17 1 1 15 2 1 15 2
