Make multiple values into one.

Derdavos — Wed, 10 May 2017 09:18:19 GMT

Hey guys

I have to make same but multiple values into one value. Like I have 100, 111, 122, 133, 100, 111, 100, 113, 112 so after I reduce it it should look like: 100, 111, 122, 133, 113. Or for an easier example: there is a lot of 'F' (stands for Female): F, F, F, F, F, F, F and it should look like: just an F.

Thank you. 🙂

Please post your example data (in a data step) so we can get a picture of what you want to do.

Use PROC SORT with the NODUPKEY option like this

data have;
input Gender $;
datalines;
F
F
F
M
M
F
F
M
M
;

proc sort data = have nodupkey out = want;
	by Gender;
run;

Here's some code that could go in a DATA step:

data new;

set have;

newvar = scan(oldvar, 1, ',');

if length(oldvar) > length(newvar) then do i=2 to countw(oldvar, ',');

next_word = scan(oldvar, i, ',');

if indexw(newvar, strip(nextword))=0 then oldvar = catx(oldvar, ',' , next_word);

end;

run;

It's untested code, so you might need to fiddle with the INDEXW function, but it probably works as is.
