Combine (Interleave) two columns, keeping all other columns, too

NKormanik — Sun, 03 Jul 2016 00:05:39 GMT

Please see the following data set:

Bob Paul 120
Tina Adele 111
Scott Joe 100
Betty Trish 97
Mark Adam 95

Three columns: Name#1, Name#2, Score.

I would like to join the columns to produce the following:

Bob 120
Paul 120
Tina 111
Adele 111
Scott 100
Joe 100
Betty 97
Trish 97
Mark 95
Adam 95

Two columns: Name#1 OR Name#2, Score

How can this be done efficiently?

Any help greatly appreciated.

Thanks!

Nicholas Kormanik

Hi,

One way to do this:

data want(keep=Name score);
set have;
array n(*) name1 name2;
do i=1 to dim(n);
Name=n(i);
output;
end;
run;

Another way:

data want;
set have;
do name = name1, name2;
    output;
    end;
drop name1 name2;
run;

Data want;

set have (rename=name1=name keep=(name score))

Have (rename=name2=name keep=(name score));

run;

You may need to play with the keep statement. I never remember if you reference a renamed variable with the original or new name in the keep section.
