...And remember that on some platforms (including yours) ICU is used, so LC_COLLATE is not particularly relevant (unless it is 'C'). See ?Comparisons and ?icuGetCollate.

Dear all, While debugging a function I realized that sort(c(" 1", " 2", "10")) do not give the same result on Windows and Linux. This is actually not surprising because white spaces are not handle in the same manner on these two platforms. But I was wondering if this behavior is also desired in R. regards, Yohan Chalabi

Yes, collation is a strange thing, and? Collation order will depend on locale settings, and there are quite a few cases where the collation order of two items is not defined. To add to the confusion, on OSX Mavericks, I see > x <- "\u0663" > y <- 3 > > x == y [1] FALSE > rank(c(x, y)) [1] 2 1 > x [1] "?" > x == y [1] FALSE > x > y [1] TRUE
