Thanks a lot Professor Ripley!
I did not go into much of the details in the help page and was hoping
somebody could have a quick answer.
The answer you provided is indeed helpful!
Thank you.

Hi,
I am wondering if there is an option to control how R sort
characters on different machines.
Yes, and it is described on the help page for sort:
The sort order for character vectors will depend on the collating
sequence of the locale in use: see 'Comparison'. The sort order
for factors is the order of their levels (which is particularly
appropriate for ordered factors).
and do study the cross-reference and its references.
Sorting on Mac OS X in UTF-8 locales seems broken (that is, the
standard C functions compare in Unicode point order irrespective of
language): we are working on a solution (the use of ICU. which can
be compiled into R >= 2.8.0).
For example, on my Mac OS X
sort(c("H", "a"), decreasing = TRUE)
[1] "a" "H"
The same command on a Linux machine gives me
sort(c("H", "a"), decreasing = TRUE)
[1] "H" "a"
I don't know if there is an option to control the behavior of 'sort'.
Well, the posting guide did ask you to do your homework, including
reading the help pages.
Thanks,
Wen
