Hi,
I have a list of ID:s (25000 st) and I now want create a new column next to the ID:S and enumerate each of this ID:n with 1-10. Like this:
ID number
1 1
1 2
1 3
1 4
1 5
1 6
1 7
1 8
1 9
1 10
2 1
2 2
2 3
2 4
2 5
2 6
2 7
2 8
2 9
2 10
an so one
I hope someone can help me with this!
/Thomas
Thanks
I am not sure that this solves my problem
i would like to write a code to enumerate 1-10 in each ID ( i only have a column with ID:s)
data want;
ser have;
by id;
if first.id then count 1 to 10
run;
It's easier if you post two data sets, one that you have and one that you want.
data want;
set have;
do number=1 to 10;
output;
end;
run;
Thanks!
Works perfectly!
