r - Is there a simpler way to translate numbers into strings? -


a vector in r

> <- c(1, 2, 3, 3, 2, 3, 1, 2, 1)

that want "translate" (temporary) vector of strings 1 becomes "foo", 2 becomes "bar" , 3 becomes "baz".

i can achieve sapply:

> sapply(a, function(x) {if (x==1) return ('foo'); if (x==2) return ('bar'); return ('baz')})  [1] "foo" "bar" "baz" "baz" "bar" "baz" "foo" "bar" "foo"

however, think there should alternative way without (what perceive misusing) sapply. case?

just try:

c("foo","bar","baz")[a] #[1] "foo" "bar" "baz" "baz" "bar" "baz" "foo" "bar" "foo"
