I can see what the problem is - we don't have the generic dispatch mechanism in place. I will add it. I think that the special casing of data frames is needed because this appears to be the (undocumented) S behaviour. A data frame anywhere in the argument list causes the result to be a data frame.
I played around with this earlier today. There's nothing special about dataframes, S does the same with any classed object. I.e. class(b)<-"my" cbind.my<-function(...)match.call() cbind(a,b) will dispatch cbind.my
Yetch! What happens when there are conflicting classes I wonder. [ Rhetorical question. ] It sounds like this might make things easier.
