if there's nothing specific for it, you could probably do it with merge?

Hi!
Given a vector (or a factor within a df),i.e. v1 <- c(1,1,1,2,3,4,1,10,3)
and a dictionary
cbind(c(1,2,3),c(1001,1002,1003))
is there a function (on the same line than recode() in car)
to get v2 as c(1001,1001,1001,1002,1003,4,1001,10,1003) ?
I'm using myself a function based on match() since
long ago (I think that thanks to advice by Prof. B. Ripley),
but would like to know if there is an standard function (i.e., like
recode()). What I'm using is:
"reclas" <- function(v, origen, imagen, directo = T, resto=1)
{
if(directo == F) {
aux <- origen
origen <- imagen
imagen <- aux
}
m <- match(v, origen, 0)
#print("match finished")
if(resto==0) v <- v*0
v[m > 0] <- imagen[m]
v
}
