Is this, what you are looking for:

x <- c("a","b","c")
lettersnum <- 1:length(letters[])
names(lettersnum) <- letters[]
lettersnum[x]
 > lettersnum[x]
a b c
1 2 3

Heinz

Heinz,

i'm not sure if the following is obviously better, but one might do
----
> b <- match(a, a)
> names(b) <- a
> b
a b c
1 2 3
