Hi,
I want to create a new variable (newvar) based on conditional logic see below - i know this would be easy but I need help.
have:
var1 var2 var3 var4 var5 var6
1 1 0 a b c
1 1 1 b b c
0 1 1 d b c
1 0 0 a b c
1 0 1 b a c
want:
var1 var2 var3 var4 var5 var6 newvar
1 1 0 a b c 1 (if var4 or var5 =a and var1 or var2 =1 then newvar=1)
1 1 1 b b c 0
0 1 1 d b c 0
1 0 0 a b c 1
1 0 1 b a c 1
thanks
It is easy. Catch the logical value of those joint conditions. It takes 1 when true zero otherwise.
data have;
input var1 var2 var3 var4 :$1. var5 :$1. var6 :$1.;
datalines;
1 1 0 a b c
1 1 1 b b c
0 1 1 d b c
1 0 0 a b c
1 0 1 b a c
;
run;
data want;
set have;
newvar = (var4 = 'a' | var5 = 'a') & (var1 = 1 | var2 = 1);
run;
