There is a warning in the help file for model.tables


     The implementation is incomplete, and only the simpler cases have
     been tested thoroughly.

     Weighted `aov' fits are not supported.

Could it be that 'simpler cases' excludes those with any NAs?  I get
an error message:

Error in replications(paste("~", paste(names(tables), collapse = "+")),  : 
	na.action must be a function

Could it simply be that na.action = na.omit doesn't make it through,
or should I be looking somewhere else?
