Note that the variable below has been generated with cut(), if that matters.

Re: [R] Problem with xtabs(), exclude=NULL, and counting NA's
>> xtabs(~wkhp, x, exclude=NULL, na.action=na.pass) > wkhp > 20 30 40 45 60 > 1 1 10 1 3 4 Thanks! I must say that this is slightly odd behavior to require both na.action= AND exclude=. Does anyone know of a justification? Shouldn't it be changed? Ah well, if R were internally consistent or corresponded to typical programming Unix practices, it just wouldn't feel the same ...
