The example is simply.But the other example:
One column: acba,coma,acmo,acmo,acba,coma
I want to replace "acba" with "aaa", "coma" with "bbb", and "acmo" with
"ddd".
Like this: aaa,bbb,ddd,ddd,aaa,bbb
How to do it?
Thanks.

you can use as.numeric(factor( )); in your example:
> ex <- sample(letters[1:3], 10, T)
> ex
[1] "b" "b" "c" "b" "a" "a" "b" "b" "a" "a"
[1] 2 2 3 2 1 1 2 2 1 1
if the order is different, use levels:
> as.numeric(factor(ex, levels=letters[3:1]))
[1] 2 2 1 2 3 3 2 2 3 3
