I don't know R... but, to my naive eye, that looks like it does neither the split nor the join. Is R one of those shell-like languages which implement lists as strings?

This isn't a problem with R, it is a problem with me not thinking. Not only did I forget the split/join, the sort function I originally used only worked because my test case happened to be in alphabetical order. I have updated the original post with functioning code.

My apologies to all of you who incorporated the broken code into your mission-critical systems.

No.

You're right. The function posted above fails because it doesn't do the split or the join. R is lovely for statistics, but it's clumsy with text, despite efforts to implement Perl-like regex capabilities.
