The following is not what I expected in sorting characters (single letters
and the same letters with preceding spaces).
Can someone enlighten me as to why the following might be a correct result
for sorting?
; x <- c(LETTERS[1:3], paste(" ", LETTERS[1:3], sep=""))
; x
[1] "A" "B" "C" " A" " B" " C"
; sort(x)
[1] "A" " A" "B" " B" "C" " C"
; sort(x, method="shell")
[1] "A" " A" "B" " B" "C" " C"
; sort(x, method="quick")
[1] "A" " A" "B" " B" "C" " C"
I would expect the result to be " A" " B" " C" "A" "B" "C" instead,
going by ASCII codes (and a quick check with S-Plus 6.2 shows that this is
what S-Plus thinks the sorted sequence is).
Thanks,
Andreas Krause
