You know, I merely forgot a smiley, there. You are right in that we should try a bit to spare the extreme susceptibility of some people! On the other hand, there should be limits to the feeling that we are always walking on eggs while writing to R-help or R-devel, some comfort and happiness is needed, after all. :-) >Yes; in this case, I propose to just amend the documentation >explainining that data.frames are treated "as matrices". Let me add a small comment about data.frames. It would be a bit awkward if a data.frame had two columns "y" and "x" (in that order) and if they were interpreted differently after matrix coercion. I guess the problem would not exist if data.frames were really interpreted as lists, the "x" and "y" columns could even appear anywhere (untested). -- François Pinard http://pinard.progiciels-bpi.ca ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
