changing a range of values

Is this what you want:
x <- c(1,1,1,2,2,3,4,4,5)
ifelse(x >= 1 & x <= 3, 1, x)
[1] 1 1 1 1 1 1 4 4 5

Hi,

If I have following vector;

x <- c(1,1,1,2,2,3,4,4,5)

and I want to change values in the range of 1 to 3 into the value 1, how can
I do that?

I tried

x[x == c(1:3)] <- c(1)

but than I get;

 x
[1] 1 1 1 2 1 1 4 4 5

R doesn't change the 2 into a 1.
But why?
