calculating number of observations by day for multiple subjects

[CMPSU]

I have a large data set that I'd like to calculate number of "feeding events" by day for 120 individuals across 90 days.

There are anywhere from 90-200 feeding events per day. 

Is there a way for SAS to "count" the number of times the EID shows up within the same date 

Example:

             EID                         TIME           Consumed

Count often brings proc Freq into play.

proc freq data=have;
   tables eid * time /list;
run;

is one way. If you want a data set you can add an out=datasetname to the option list after the / .

Several other procedures would work as well.

This worked! follow up question: How can a calculate average of # observations per day

EXAMPLE: 840003208080904 had and average of 34 recorded events /day across all 100 days
