I'm bold and say (for the moment) that the above line has always been very dubious if not misleading, and this "fact" is now finally revealed by the warning > Warning message: > In `class<-`(x, unique.default(c("AsIs", oldClass(x)))) : > Setting class(x) to multiple strings ("AsIs", "classRepresentation", > ...); result will no longer be an S4 object So, yes, the change has been on purpose to warn about problems, you'd get later when trying to work with 'z'. > [[alternative HTML version deleted]] (your fault: do use plain text aka MIME time 'text/plain')) ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
