proc transpose with two id variables

michtka — Tue, 03 Apr 2012 00:21:31 GMT

Hi everyone, after doing proc freq to a demog dataset I obtain new4f:

agex treat Sex COUNT

13-24 drug F 4

13-24 drug M 2

13-24 PLA F 2

13-24 PLA M 4

less than 13 drug F 2

less than 13 drug M 2

less than 13 PLA F 1

less than 13 PLA M 2

Then, after doing proc sort and proc transpose I would expected the next datase *:

proc sort data=new4f out=new4fs;

by agex;

run;

proc transpose data=new4fs out=new4fst (drop=_label_ _name_);

by agex;

id treat sex;

var count;

run;

I would expected somethign like :

*dataset new4fst

agex drugf drugm plaf plam

13-24 4 2 2 4

less than 13 2 2 1 2

but, windows sas log shown the next error:

151 by agex ;

152 id treat sex;

---

200

ERROR 22-322: Expecting ;.

ERROR 200-322: The symbol is not recognized and will be ignored.

what I am doing wrong?

Thanks in advance.

how about:

data have;

input agex $20. treat $ Sex $ COUNT;

cards;

13-24 drug F 4

13-24 drug M 2

13-24 PLA F 2

13-24 PLA M 4

less than 13 drug F 2

less than 13 drug M 2

less than 13 PLA F 1

less than 13 PLA M 2

;

run;

data temp;

set have;

two=cats(treat,sex);

run;

proc transpose data=temp out=want(drop=_:) ;

by agex;

var count;

id two;

run;

proc print;run;

drug drug

Obs agex F M PLAF PLAM

1 13-24 4 2 2 4

2 less than 13 2 2 1 2

It is very strange. I tested your code. No problem.

data have;
input agex $20.  treat $      Sex $          COUNT;
cards;
     13-24           drug         F                4
     13-24           drug         M                2
     13-24           PLA          F                2
     13-24           PLA          M                4
     less than 13    drug         F                2
     less than 13    drug         M                2
     less than 13    PLA          F                1
     less than 13    PLA          M                2
  ;
run;



 

proc transpose data=have out=want(drop=_:) ;
by agex;
var count;
id treat sex;
run;

hi ... two ID variables, online doc does say "one or more" ...

ID variable(s);

variable(s) names one or more variables whose formatted values are used to form the names of the variables in the output data set.

and ...

When you specify multiple ID variables, conformance to the SAS variable naming convention will be imposed on the components of the variable name, using the formatted value of each ID variable, and also on the name composed from the ID variable values and the PREFIX, DELIMITER, and SUFFIX options. The resulting name will be truncated to a length appropriate for the VALIDVARNAME option setting.

nice solution that doesn't require the prior concatenation of the variable values
