How to group values within a column in R?

Question

I have a data set where I have a column that has values 0 - 1,000. I want to group the values so 0 - 200 is denoted as 1, 200 - 600 as 2, and 600 - 1,000 as 3. Then I want the values 1,2,3 in one column. How do I do this? I am new to R.

Answer 1

Use findInterval . Example:

x <- c(0, 199, 200, 201, 599, 600, 601, 1000)
findInterval(x, c(0, 200, 600))
#[1] 1 1 2 2 2 3 3 3
