I believe the CLASSDATA option in PROC TABULATE lets you specify which values will show up in the table, including unobserved values. http://support.sas.com/onlinedoc/913/getDoc/en/proc.hlp/a002473736.htm#a003069171 I'm not aware of any way to do this in PROC FREQ, though. -- James Reilly Department of Statistics, University of Auckland Private Bag 92019, Auckland, New Zealand ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
