Given a table like such:
Obs A B C D E
1 1 2 1 1 2
2 2 2 1 2 2
3 2 3 3 2 2
4 1 2 3 1 1
how do i create a column , summing the number of times the value of 1 occurs in the row?
Like this.
Obs A B C D E Count
1 1 2 1 1 2 3
2 2 2 1 2 2 1
3 2 3 3 2 2 0
4 1 2 3 1 1 3
Hi,
If the table values are only 1 digit numbers (0-9), then a simple count function can give the answer. I would combine all variables into a character string and count number 1 there.
data want;
set have;
char= catx(',', a, b, c, d, e);
count= countc(char, '1');
proc print; run;
You can use SAS array and examine the values of each column to match with 1, and count them.
data have;
input A B C D E;
datalines;
1 2 1 1 2
2 2 1 2 2
2 3 3 2 2
1 2 3 1 1
;
run;
data want;
set have;
array x[*] A B C D E;
count = 0;
do i = 1 to dim(x);
if x[i] = 1 then count + 1;
end;
drop i;
run;
proc print data = want;
run;
