I have the following data:
ID | flg1 | flg2 | flg3 |
60038807 | 1 | 0 | 0 |
60038807 | 0 | 0 | 0 |
60038807 | 0 | 1 | 0 |
Now I would like to "summarize it" so it looks like this:
ID | flg1 | flg2 | flg3 |
60038807 | 1 | 1 | 0 |
So one row with a "1" in all columns where it has a 1.
proc summary data=have nway;
class id;
var flg1-flg3;
output out=want max=;
run;
You don't really explain what you mean by "summarize" so I have chosen to compute the maximum of your zeros and ones. If you want something different, you can just change the statistic in the output statement from max= to any other statistic you want.
