There's got to be a better way to use order() on a matrix than this: > y 2L-035-3 2L-081-23 2L-143-18 2L-189-1 2R-008-5 2R-068-15 3L-113-4 3L-173-2 398 1 1 2 2 1 1 2 2 857 1 1 2 2 1 2 2 2 911 1 1 2 2 1 2 2 2 383 1 1 2 2 1 1 2 2 639 1 2 2 1 2 2 1 2 756 1 2 2 1 2 2 1 2 3L-186-1 3R-013-7 3R-032-1 3R-169-10 X-002 X-087 398 1 2 2 2 1 2 857 1 2 2 2 1 2 911 1 2 2 2 1 2 383 1 2 2 2 1 2 639 2 2 1 2 1 2 756 2 2 1 2 1 2
> y[order(y[,1],y[,2],y[,3],y[,4],y[,5],y[,6],y[,7],y[,8],y[,9],y[,10],y[,11],y[,12],y[,13],y[,14]),] 2L-035-3 2L-081-23 2L-143-18 2L-189-1 2R-008-5 2R-068-15 3L-113-4 3L-173-2 398 1 1 2 2 1 1 2 2 383 1 1 2 2 1 1 2 2 857 1 1 2 2 1 2 2 2 911 1 1 2 2 1 2 2 2 639 1 2 2 1 2 2 1 2 756 1 2 2 1 2 2 1 2 3L-186-1 3R-013-7 3R-032-1 3R-169-10 X-002 X-087 398 1 2 2 2 1 2 383 1 2 2 2 1 2 857 1 2 2 2 1 2 911 1 2 2 2 1 2 639 2 2 1 2 1 2 756 2 2 1 2 1 2 Thanks for any suggestions! -Aaron [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
