changing values

Dear R list members,
I have a factor vector with levels 1, 2, 3 and 4. I want to re-group it: 1

and 2 will be 1 and 3 and 4 will be 2, e.g.:

x <- c(1, 1, 1, 2, 3, 2, 3, 4, ... )
x <- factor(x)
What I have to do create a new vector where 1 1 1 2 3 2 3 4 ... is

transformed in 1 1 1 1 2 1 2 2 ... ? (I have more than 200 lines in my
dataframe)

Thanks in advance.

I don't know if it is the best way to do it, but it works:

x <- as.numeric(x)
x[x<=2] <- 1
x[x>2] <- 2
x <- as.factor(x)

Best regards,

Philippe Grosjean
