Depending on the locale the items may not sort in ASCII order. For example, a European-latin locale may have some letters in different places than ASCII. You have to check what is being sorted (e.g., map the stuff to UTF8 binary). You might also find that input generated on windog has "smart spaces" in it from the generating program (e.g., Excell) that are something like \xA0 instead of \x20 (32d) used in ASCII spaces. Suggestion: Validate the data with something like "od -cx" on linux so you know what you are sorting. Then dump it out as hex in R [sorry, I have no idea how to do that] and see if what you are sorting matches. After that validate the LOCALE setting on both sides. If all of those turn up the same raw data then you've found a bug in R -- or at least need to read some fine print in the lexical sort docs. -- Steven Lembark 85-09 90th St. Workhorse Computing Woodhaven, NY, 11421 lemb...@wrkhors.com +1 888 359 3508 ______________________________________________ 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.
