Martin, my feedback would be that changes that improve the efficiency of data frames are very welcome. And if implementing them in a sensible manner breaks some old code in a way that is not obnoxious, i.e., by making some previously sensible behavior less sensible, then it is worthwhile to do so. (Where sensible is defined in terms of the new semantics.) As a particular example, I would consider it OK to break old code that relied on default row names being character data. (But this may not be necessary). -- Tony Plate > > Martin > > ______________________________________________ > R-devel@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-devel > ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
