My favorite SAS proc: proc freq

No doubt, my favorite proc step is proc freq. It is extremely simple, but therein lies its beauty: it's fast to run and easy to understand.

I've found raw proc freq output to be a terrific starting point for conversations on data cleaning or data exploration, no matter who is involved in the conversation:

PROC freq data=NAME;
