Hello.
I have a problem using sort() in windows 2000 and windows NT 4.0, running R 1.8.0 on both. I want to sort a vector of characters names, where I have used "Scandinavian" letters, like 'Æ', 'Ø', and 'Å' (for those who cannot display these letters this question seems rather meaningless, i guess). Windows 2000 sorts the vector like I am used to from other software, with 'Å' as the last letter in the alphabet, while windows NT has "Å" just after "A", and "Ø" following "O".
Is there a way to solve this problem (other than replace the Scandinavian letters)?
A short example: sort(c('a','p','å')) # on windows 2000: [1] "a" "p" "å"
# on windows NT [1] "a" "å" "p"
Thanks in advance
?sort tells us:
"The sort order for character vectors will depend on the collating sequence of the locale in use: see Comparison."
and ?Comparison points you to ?locales which gives an example:
Sys.setlocale("LC_COLLATE", "C") # turn off locale-specific sorting

Thanks for the help, it worked great. However, it appers that using the Sys.setlocale("LC_COLLATE", "C") makes R sort the vector in a new way, different from the two mentioned above. But since R sorts character vectors at same manner on both W2K and Window NT, after writing Sys.setlocale("LC_COLLATE", "C"), it is sufficient for me.
