[R] recoding variables

[Roger D. Peng]

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].

I literally have no idea how to proceed--could anyone possibly advise me?  Please copy me on any responses, as I have just subscribed to the R-help email list but don't know whether the subscription has gone through yet.
