Hello All,
hoping someone can help with this little problem. I have a dataset which looks something like this
age_1 | age_2 | gender | Mean |
1 | 0 | 0 | 15 |
0 | 1 | 0 | 32 |
0 | 0 | 1 | 23 |
created from a PROC MEANS command and I would like to convert it to a dataset like this
Var | Mean |
age_1 | 15 |
age_2 | 32 |
gender | 23 |
I had though maybe an ARRAY approach would work, but can't quite figure out how to pass the variable name from the array into a new variable. Perhaps someone could help?
Many thanks, Chris
data have; input age_1 age_2 gender Mean; cards; 1 0 0 15 0 1 0 32 0 0 1 23 ; run; data want; set have; length var $ 40; array x{*} age_1 age_2 gender; do i=1 to dim(x); if x{i} then var=vname(x{i}); end; drop i; run;

Use array:
data want(keep=var mean);
do i=1 by 1 until (last);
set have end=last;
array temp age_1--gender;
var=vname(temp(i));
output;
end;
run;
Or transpose:
proc transpose data=have out=need(where=(col1=1)) name=var;
by mean notsorted;
run;
data have; input age_1 age_2 gender Mean; cards; 1 0 0 15 0 1 0 32 0 0 1 23 ; run; data want; set have; length var $ 40; array x{*} age_1 age_2 gender; do i=1 to dim(x); if x{i} then var=vname(x{i}); end; drop i; run;

many thanks slchen and Xia I'm very grateful you spent time to consider and answer the question. It was the vname function that is key!
