That's an assumption. The help pages are quite clear about making assumptions. The only way this could be a 'bug' is if you can show that the sort order in R is different from the lexicographic sort order using the collating sequence of the locale in use. But even my command line 'sort' agrees: $ sort < f1.txt _1_ 1_9 2_9 now add the trailing a: $ sort < f1.txt 1_9a _1_a 2_9a [ I had a thought maybe it was because _ is sometimes used to break thousands in numeric formats, but I can't get any obvious consistency out of that hypothesis ] Barry ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
