Thank you, Greg.

BTW, given the thread, this is a typical example where it might
be very useful to add the following two concepts to the 
   mixedsort.Rd file in gtools :

\concept{natural sort}
\concept{dictionary sort}

so that mixedsort() will be quickly found by help.search("natural sort")
and possibly also via the java search from the HTML help interface?
(I never use it; I use help.search() {or then RSiteSearch()}
 exclusively.)
