I would like to be able to join variables 1-4 into one variable based on the value.
data have;
input var1 var2 var3 var4;
cards;
1 91 98 1
2 1 91 2
2 2 91 2
1 98 2 91
2 2 2 2
;
run;
I want the output to be set so if there is a value of '1' in var1, var2, var3, or var4, the output will be 1. If there is not a value of '1' in any of the four variables, I want the output to be 0. I'm not sure how to go about this. Thank you!
Try this
data have;
input var1 var2 var3 var4;
cards;
1 91 98 1
2 1 91 2
2 2 91 2
1 98 2 91
2 2 2 2
;
run;
data want;
set have;
array var var:;
v = (1 in var);
run;
Result:
var1 var2 var3 var4 v 1 91 98 1 1 2 1 91 2 1 2 2 91 2 0 1 98 2 91 1 2 2 2 2 0
data have;
input var1 var2 var3 var4;
cards;
1 91 98 1
2 1 91 2
2 2 91 2
1 98 2 91
2 2 2 2
;
run;
The example code was messed up. This is more accurate.
Try this
data have;
input var1 var2 var3 var4;
cards;
1 91 98 1
2 1 91 2
2 2 91 2
1 98 2 91
2 2 2 2
;
run;
data want;
set have;
array var var:;
v = (1 in var);
run;
Result:
var1 var2 var3 var4 v 1 91 98 1 1 2 1 91 2 1 2 2 91 2 0 1 98 2 91 1 2 2 2 2 0
