Hello.  I have a dataset where I want to display the number of
observations for 2 different variables and the difference between them.
 Right now I am using the following code but I am not sure about how to
get the difference.  Thanks in advance.


proc means data=combined N;
var DUBPARTS PARTICIPANTS;
label DUBPARTS='Count of Person_ID from original dataset'
      PARTICIPANTS='Count of unique Person_ID';
title 'Breakdown of participants';
run;
