Hi everyone, 

 

I'm trying to fill in empty cells using the value from the first non-missing cell to the left of that empty cell in each row. The table runs from January 1, 2014 through August 1, 2018. For example:

I tried:

 

data desiredtable;

set rawtable;

if variable=. then lag(variable);

end;

run;

 

But seems like this only works if the table was set up in long format vs. wide format. 

 

Any help is appreciated. Thanks.

data HAVE;
  input A B C D E F G H  ;
  cards;
. 1 . 2 3 . . .
run;
data WANT;
  set HAVE;
  array ARR [8] A -- H ;
  do I=2 to 8;
    if ARR[I]=. then ARR[I]=ARR[I-1];
  end;
run;
