Hi there,
For your kind information, I am trying to create a summary of flags per record where flags are coming from multiple rows for each ID as shown in the data. Can anybody help me to write sascode to move forward to achieve the goal (without splitting and merging the tables)
data have;
input id $ flag1 flag2 flag3 flag4 ;
datalines;
101 1 0 0 1
101 0 1 0 0
102 0 0 0 1
102 0 0 1 0
102 1 0 1 0
103 1 1 0 0
103 1 1 1 0
103 1 0 0 0
;
run;
data want;
input id $ flag1 flag2 flag3 flag4 ;
datalines;
101 1 1 0 1
102 1 0 1 1
103 1 1 1 1
;
run;
Thank you in advance for your kind reply.
Regards,
One way of several
proc summary data=have nway; class id; var flag: ; output out=want (drop=_:) max=; run;
One way of several
proc summary data=have nway; class id; var flag: ; output out=want (drop=_:) max=; run;
Another way if you prefer proc sql-
proc sql;
create table want as select id, max(flag1) as flag1, max(flag2) as flag2, max(flag3) as flag3, max(flag4) as flag4 from have group by id;
quit;
