As this letter did not generate any reply, I presumed the ideas have not be rejected, on the premise that if they have been, someone would have been kind enough to tell me :-). So, today, I went forward and added Duff's device within arithmetic.c. There might have been operational or experimental error, of course, as I'm far from mastering R installation matters. But if there were no such error, I'm now reporting, for the record, that Duff's device does _not_ yield an interesting speedup. -- François Pinard http://pinard.progiciels-bpi.ca ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
