Hello,

 

So I have a dataset like below:

 

id_var     year     measures

1             2014               20

1             2015               20

2             2015               23

3             2014               17

 

 

And I want get rid of duplicate id_vars but KEEP the one with the year 2015. I know nodupkey gets rid of duplicates based on the by variable in proc sort, but i don't know how to reference the specific year value. Any help would be great.

 

Thanks.

Double sort. 

Sort first with descending year, then sort with nodupkey. 

 

Proc sort data=have;

by id descending year;

 

proc sort data=have nodupkey;

by id;

run;
