Hi, folks,
I find that there are lots of duplicated observations in my data sets. Is there a code to delete them automatically?
Thanks!
Wu
proc sort data=yourdatafile nodupkey;
by thevariablelistwithinwhichyoudontwantduplicates;
run;
may do what you want.
Possibly more effecient in some situations:
Proc sql;
Create table nodup as
select distinct *
from yourdataset;
quit;
