Good day! My data looks like this:
ID B1 B2 B3
1 1 2 3
2 4 5 6
3 7 8 9
I would like it to look like this:
ID B# Content
1 1 1
1 2 2
1 3 3
2 1 4
2 2 5
2 3 6
3 1 7
3 2 8
3 4 9
Could you pls help me. Thanks!
In addition to transposing, you could do it in a data step. I assume your last row is a typo, though. I don't know where the b# = 4 would come from.
data have;
input ID B1 B2 B3;
datalines;
1 1 2 3
2 4 5 6
3 7 8 9
;
data want(drop = b:);
set have;
array b{3};
do num_b = 1 to 3;
content = b(num_b);
output;
end;
run;
Without test data in the form of a datastep, this is just a guess:
proc transpose data=have out=want; by id; var b:; run;

thank you so much! the last one was a typo
You're welcome. @RW9' s solution would probably work for you, too, and you should probably get familiar with how proc transpose works since there are times when it will be far easier than a data step approach.
