You are looking for cut():

(tst <- cut(1:11, c(-Inf, 3, 5, Inf)))
[1] (-Inf,3] (-Inf,3] (-Inf,3] (3,5](3,5](5,Inf] (5,Inf] (5,Inf]
[9] (5,Inf] (5,Inf] (5,Inf]
Levels: (-Inf,3] (3,5] (5,Inf]

[1] "factor"
hope this helps. spencer graves

Basically, you want to use cut(). For example,
x <- 1:20
cut(x, c(0, 8, 15, 20))
This divides x into a factor with levels (0,8], (8,15], and (15,20].
