Passing table the output of model.frame would still allow the use of a

Fair enough, this qualifies as a workaround, and IMO this is how xtabs
should handle it internally to allow writing xtabs(~data, na.action =
na.pass) -- or at least xtabs(~data, na.action = na.pass, exclude =
NULL) if backward compatibility is desired. Would anyone with write
access to R's SVN repo care enough about this situation to review a
patch? Thanks.
