Have:
category | group | frequency | percent |
female | treatment | 3 | 33.33 |
male | treatment | 6 | 66.67 |
female | placebo | 1 | 33.33 |
male | placebo | 2 | 66.67 |
Want:
category | treatment_frequency | treatment_percent | placebo_frequency | placebo_percent |
female | 3 | 33.33 | 1 | 33.33 |
male | 6 | 66.67 | 2 | 66.67 |
Tried:
proc transpose data=c.demographics_freq out=c.test prefix=group_;
by category ;
id frequency percent;
var group;run;
Hi @monday89
It seems that you already posted this question:
https://communities.sas.com/t5/SAS-Programming/proc-transpose-many-columns/m-p/611836
There are many answer attempts. Please check them.
This one for example should work. NB: you can't do that in a single proc transpose.
data demographics_freq;
input category $1-6 group $8-16 frequency 18 percent 20-24;
cards;
female treatment 3 33.33
male treatment 6 66.67
female placebo 1 33.33
male placebo 2 66.67
;
run;
data c.test;
merge c.demographics_freq (where=(group="treatment") rename=(frequency = treatment_frequency percent = treatment_percent))
c.demographics_freq (where=(group="placebo") rename=(frequency = placebo_frequency percent = placebo_percent));
by category;
drop group;
run;
ED has already given you a great solution.
Another one is double transpose.
data demographics_freq;
input category $1-6 group $8-16 frequency 18 percent 20-24;
cards;
female treatment 3 33.33
male treatment 6 66.67
female placebo 1 33.33
male placebo 2 66.67
;
run;
proc sort data=demographics_freq;by category group;run;
proc transpose data=demographics_freq out=test;
by category group ;
var frequency percent;
run;
proc transpose data=test out=want delimiter=_;
by category;
id group _name_;
var col1;
run;
You already have two good solutions, but here is a third that would also work and can easily accommodate more variables:
data demographics_freq;
input category $1-6 group $8-16 frequency 18 percent 20-24;
cards;
female treatment 3 33.33
male treatment 6 66.67
female placebo 1 33.33
male placebo 2 66.67
;
run;
filename tr url 'https://raw.githubusercontent.com/art297/transpose/master/transpose.sas';
%include tr ;
%transpose(data=demographics_freq, out=want, by=category, sort=yes,
var=frequency percent, id=group, delimiter=_, var_first=no)

Here is a solution building upon your line of thought. I used a macro to cycle through the two analysis variables, however, the non-macro code is in the comments below it
data have;
input category $1-6 group $8-16 frequency 18 percent 20-24;
cards;
female treatment 3 33.33
male treatment 6 66.67
female placebo 1 33.33
male placebo 2 66.67
;
run;
proc sort; by category; run;
%let vars=%str(frequency percent) ;
%macro trans;
%local i _var;
%do i=1 %to %sysfunc(countw(&vars));
%let var = %scan(&vars, &i);
proc transpose data=have out=&var (drop=_name_) suffix=_&var;
by category ;
id group;
var &var;
run;
%end;
data want;
merge &vars;
by category;
run;
proc print;
id category;
run;
%mend;
%trans;
/*
proc transpose data=have out=frequency (drop=_name_) suffix=_frequency;
by category ;
id group;
var frequency;
run;
proc transpose data=have out=percent(drop=_name_) suffix=_percent;
by category ;
id group;
var percent;
run;
data want;
merge frequency percent;
by category;
run;
