Re: [R] Sorting of character vectors

Thanks for all suggestions. With my build (from the CRAN repo) I don't get ICU support, and setting LC_COLLATE to "C" did not help. > capabilities("ICU") ICU FALSE > sessionInfo() R version 3.3.2 (2016-10-31) Platform: x86_64-pc-linux-gnu (64-bit) Running under: Ubuntu 14.04.5 LTS locale:

Re: [R] Sorting of character vectors

Hello, What is your sessionInfo()? With me it works as expected: > sort(c("-", "+")) [1] "-" "+" > sort(c("+", "-")) [1] "-" "+" > x5 <- c("+Aa","-Ab") > sort(x5) [1] "-Ab" "+Aa" > sessionInfo() R version 3.3.2 (2016-10-31) Platform: x86_64-w64-mingw32/x64 (64-bit) Running under: Windows 7 x64

[R] Sorting of character vectors

I just got caught by the way in character vectors are sorted. It seems that on my machine "sort" (and related functions like "order") only consider characters related to punctuation (at least here the "+" and "-") when there is no difference in the remaining characters: > x1 <- c("-A","+A")
