sasCommunity Tip of the Day

 proc sort data=sashelp.class
   by sex;
proc rank data=class
          out=rank5(where=(rankwt le 5))
   by sex;
   ranks rankwt;
   var weight;

Did you know that you can use PROC RANK to create subsets of observations within a group based on the value of an analysis variable? In this example we want the top 5 heaviest weights within each level of SEX. Remove the keyword DESCENDING to save the 5 lightest weights.

Adding the TIES=LOW option on the PROC RANK statement allows you to collect ties as well (you may end up with more than just the specified number of observations).
