The explanations from you are Brian are helpful, thanks. I was aware that the issue is the internal representation of S4 objects and was hoping there might be a cheap work around until a new SEXP comes around. It seems that S4 instances are less trivial to detect than one might expect before actually trying it. I suppose one work around is to have an S4Basic class that defines methods for match(), c(), etc and raises an error. Then extending this class gives you some protection. + seth ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
