I have a large data that includes multiple observations for each ID.
If I only wanted to select the first entry of each ID, then the below code works.
If I wanted to select the first 5 entries of each ID, then what coding could I use?
Thanks for your help in advance.
data want;
set have;
by id;
if first.id;
run;

You have to count the obs per ID, code is untestet:
data want;
set have;
by id;
length counter 8;
retain counter;
if first.id then counter = 0;
counter = counter + 1;
if counter <= 5;
run;
