Hi All,
I have 3 values corresponsing to each ID.
I am looking for output as lowest V column corresponding ID.
In the output of Final column, Value should be picked always on V3 , V2, V1 sequence priority.
If all three is not null then V3
if V1 and V2 is not null and V3 is nullthen V2
if v2 and v3 is null and V1 is not null then v1
note : ID is duplicated in rows.
Source :
data test;
infile datalines dlm=' ' dsd;
input id $ V1 $ V2 $ V3 $;
datalines;
1 x y z
2 x y
3 x
1 x y
3 x y z
;
run;
expecting output :
ID Final
1 z
2 y
3 x
1 y
3 z

if not missing(v1) and not missing(v2) and not missing(v3) then output=v3;
if V1 and V2 is not null and V3 is nullthen V2
if v2 and v3 is null and V1 is not null then v1
These are obvious modifications of the code above.
An easy-to-understand approach:
final = v3;
if final = " " then final = v2;
if final = " " then final = v1;
Hello,
Another solution using an array and coalescec function to retrieve the first non missing element :
data test;
infile datalines dlm=' ' dsd;
input id $ V1 $ V2 $ V3 $;
length final $1.;
array v(*) v3-v1;
final=coalescec(of v(*));
datalines;
1 x y z
2 x y
3 x
1 x y
3 x y z
;
run;
