[R] rearrange problem

[jim holtman]

Is this what you want:

> n <- 10
> m <- 4
> x <- replicate(n, paste(letters[sample(1:26,m)], collapse=''))
> x
 [1] "zmld" "tlme" "fonb" "aqwn" "onxl" "rpfx" "sler" "cvom" "ilme" "nbge"
> x.sort <- sapply(x, function(.str){
+     paste(sort(strsplit(.str, '')[[1]]), collapse='')
+ })
> x.sort
  zmld   tlme   fonb   aqwn   onxl   rpfx   sler   cvom   ilme   nbge
"dlmz" "elmt" "bfno" "anqw" "lnox" "fprx" "elrs" "cmov" "eilm" "begn"
