If your data is numeric then rank(-x) would be a bit shorter. I agree, however, that it would be nice to support decreasing = TRUE as an arg to rank, not only for the above reason but also for consistency with order which already supports such an argument. ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-devel
