Using prefix before a variable in proc transpose

georgel — Wed, 18 May 2022 17:11:42 GMT

Dear Users,

I would like to have a prefix before each variable is created instead of _1, _2, _3

when I run the following: (actually BHARced_1 BHARced_2 BHARced_3 and then for the second BHRced_1..

options mprint;
*move the quarters as columns;
%let varlist = BHARced BHRced;

%macro rename;
   %let word_cnt=%sysfunc(countw(&varlist)); 
   %do i = 1 %to &word_cnt; 
     %let temp=%qscan(%bquote(&varlist),&i);
	    proc transpose data=dsf4(keep=cusip year_performance &temp )
					out=performance_&i
					name= &temp;
					id year_performance;
	                *prefix= &name;
					by cusip ;
					
	    run;
        data performance_&i(rename=(_1= 1_&temp _2= 2_&temp _3=3_&temp));/*there is a proble, here*/
		     set performance_&i;
		run;

   %end;
%mend rename;
%rename;

Log output:

MPRINT(RENAME):   proc transpose data=dsf4(keep=cusip year_performance BHARced )
out=performance_1 name= BHARced;
MPRINT(RENAME):   id year_performance;
MPRINT(RENAME):   *prefix= &name;
MPRINT(RENAME):   by cusip ;

Thank you very much PaigeMiller for your great guidelines

/*there is a proble, here*/

Whenever code isn't working right, we normally ask to see the LOG. We need to see the ENTIRE log for this macro, every single line, every single character; do not pick and choose parts of the log to show us. Copy the log as text and paste it into the window that appears when you click on the </> icon.

In addition, since it is a macro problem, please run this line and then run your code again and show us that log.

options mprint;

From now on, we expect you to show us the LOG every single time you have an error or problem.

PREFIX= is an option of the PROC TRANSPOSE statement.

Prefix option goes into the PROC statement.

This example will PREFIX the name of the variable with ABC before the value of the ID variable.

proc transpose data=sashelp.class(obs=5)
     out =trans prefix=ABC;
   by name;
   var age;
   id sex;
run;

The obs limit is just to make a very small set easy to read.

I suspect that you would be a lot better served to use PROC SUMMARY and the IDGROUP concept to transpose your data since this will allow you to transpose multiple variables at once.
