Hi All,
I am stuck in a problem of creating a single column data (B) which depends on the max value in each row of original data (A). Data A is -
Data A:
v1 v2 v3 v4
1 2 3 4
2 3 4 1
6 7 2 4
Data B should take the max from each row of Data A and then create the corresponding column as value in Data B:
Col
v4
v3
v2
Is this possible to do?
KR
SK
Here is a way.
data want;
length Col $32;
set have;
array k[*] V1 - V4;
Max = Max(of k[*]);
Pos = whichN(Max, of k[*]);
Col = vname(k[Pos]);
keep Col;
run;
Hope this is an acceptable answer.

What if you have ties?
Data A:
v1 v2 v3 v4
1 2 3 4
2 3 4 1
6 7 4 4
It is IML thing: data DataA; input v1 v2 v3 v4; cards; 1 2 3 4 2 3 4 1 6 7 2 4 ; run; proc iml; use DataA; read all var _num_ into x[c=vnames]; close; col=vnames[x[,<:>]]; create max from col; append from col; close; quit; data want; merge DataA Max; run;
