Hi All,
Below is the example data.
data have;
infile datalines missover;
informat v1 -v5 $2.;
input v1-v5;
cards;
A A B A A
X A Y X Y
S M K H A
X A X
A B B
;
run;
I want to get the result in another column V6:
first row : A/B
Second row: X/A/Y
Third Row : S/M/K/H/A
Fourth Row: X/A
Fifth Row : A/B
Thanks in advance!
Turn the duplicates into missing values (empty strings) and concatenate what's left.
data want;
set have;
array a v1-v5;
do i = 2 to dim(a);
if whichc(a{i}, of a{*}) < i then call missing(a{i});
end;
length x $10;
x = catx("/", of a{*});
drop i v:;
run;
