If we know they are integer values only then this returns
the desired vector
replace(x, x %in% 1:3, 1)
or this overwrites the input:
x[x %in% 1:3] <- 1

Is this what you want:

[1] 1 1 1 1 1 1 4 4 5

try this:
x <- c(1,1,1,2,2,3,4,4,5,3.2,0.5)
x[x >= 1 & x <= 3] <- 1
x
I hope it helps.

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,

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?
