Dear SAS Community,

I have the following problem to solve. I have a data set in which the informations about the measurement sides are stored. The data set looks like this:

 

id	subid	        side	        var1
1	1		1		3
1	2		2		3
1	3		2		3
2	1		2		5
2	2		0		5
3	1		1		4
3	2		0		4
3	3		1		4
3	4		1		4
3	5		1		4
4	1		0		0
5	1		1		1


Side 
0=no value
1=left
2=right

var1
0=no value
1=one sided left
2=one sided right
3=both sides
4=one sided left and no value
5=one sided right and no value
6=both sides and no value

 

How can I automate the function to query all the values of the variable "Side" and then save the result according to the attached coding for the total group.

 

Thanks in advance for your help.

Hi,

not really clear to me what you want to achieve.

Here's my best try using your description

PROC FORMAT;
   VALUE Side 
      0='no value'
      1='left'
      2='right'
   ;
   VALUE var1_
      0='no value'
      1='one sided left'
      2='one sided right'
      3='both sides'
      4='one sided left and no value'
      5='one sided right and no value'
      6='both sides and no value'
   ;
run;

DATA have;
INPUT id	subid side var1;
FORMAT side side. var1 var1_.;
DATALINES;
1	1		1		3
1	2		2		3
1	3		2		3
2	1		2		5
2	2		0		5
3	1		1		4
3	2		0		4
3	3		1		4
3	4		1		4
3	5		1		4
4	1		0		0
5	1		1		1
;
RUN;

PROC SQL;
   CREATE TABLE want AS
      SELECT DISTINCT side,var1
      FROM have
      ORDER BY side,var1
   ;
QUIT;

The issue is that I need to create the variable "var1" according to the above description. Unfortunately the var1 is not present.
