Cut a vector of numbers into interval factors.

Source: R/factor.R

Three types of labels (levels) are supported: “cut.default” (Interval labels returned by cut as default), “left” (Left boundary of intervals), and “right” (Right boundary of intervals).

cutInterval(
  x,
  step = 1,
  labelOption = c("cut.default", "left", "right"),
  include.lowest = FALSE,
  right = TRUE,
  dig.lab = 3,
  ordered_result = FALSE,
  ...
)
