Hallo to everyone.
I have this problem. I have a big data set so this i will try to explain you it was difficult to be implemented by hand.
First of all i have one data set which looks like:
qq1 qq2 qq3 qq4
1
0
0
2
11
i want to pick up all the variables in one new column
like
qq
1
0
0
2
11
from the first table if one column value is not missing means that all the other columns are missing in the same row
thank you in advance
Hallo @Barney1998,
If qq1 - qq4 are numeric variables, you can use the COALESCE function to obtain the first non-missing value:
data have;
input qq1-qq4;
cards;
1 . . .
. 0 . .
. 0 . .
. . 2 .
. . . 11
;
data want(drop=qq1-qq4);
set have;
qq=coalesce(of qq1-qq4);
run;
For character variables there is the similar COALESCEC function.
