have a look at ?cut(); for instance,
x <- sample(1000, 20, TRUE)
x
cut(x, c(0, 300, 600, 1000), c("A", "B", "C"))
I hope it helps.
Best,

hello all,
I have a data frame and I want to create a column which assigns a letter
based upon the value in another column. The data column has velocities
ranging from 0 to 1000. So for example, for velocities between 0 and 300
I'd like to assign the letter "A" in the new column, for 300-600, "B" and so
on and so forth. How would I do this?
Thank you very much!
