Soyeon -
It sounds like you want a combination of a numerical
sort and a lexigraphical sort. I think they need to
be done separately, and then joined back together:
myvec = scan(,what='')
1: 4 5 6 8 9 11 Y 1 13 15 16 20 X 2 3 10 14 19 XY 7 12 18 17 22 21
26:
Read 25 items
myvecn = as.numeric(myvec)
Warning message:
NAs introduced by coercion
c(sort(myvecn),sort(myvec[is.na(myvecn)]))
[1] "1" "2" "3" "4" "5" "6" "7" "8" "9" "10" "11" "12" "13" "14" "15"
[16] "16" "17" "18" "19" "20" "21" "22" "X" "XY" "Y"

Dear All,
I want to sort a character type vector.
the vector is
[1] 4 5 6 8 9 11 Y 1 13 15 16 20 X 2 3 10 14 19 XY 7 12 18 17 22
[25] 21
and I want to sort 1-22 X Y XY or 1-22 X XY Y.
How can I do that?
Thanks,
