How to make Proc Freq levels table for one variable GIVEN another variable?

[whoisyourmother]

I need to make a proc freq levels table for a variable "type", but only for entries that are ' USA ' under the "place_of_origin" variable.

Right now I'm doing

proc freq data=CarsVROOM nlevels;
tables type;
run;

and it shows me the freq table for all the "Type"s, but I want to see the freq table for all the "Type"s only for ' USA ' objects. What options do I add to the tables statement? Thanks 🙂

I think you just need to include the where clause. Try this:

proc freq data=CarsVROOM nlevels;
where place_of_origin = 'USA';
tables type;
run;
