[datatable-help] creating levels for a variable

[el_alisio]

Hi Carl,

you may want to check out the cut-function:

library("data.table")
dt <-  data.table(a = 1:10, b = sample(c(200:50000), 10), c = 21:30)
dt[, level := cut(b, breaks = c(0, 12000, 34000, max(b)),
                  labels = c("first", "second", "third"))]

Cheers,

Jannes
