discretization

Usage

discretize_vector(
  x,
  n,
  method = "natural",
  breakpoint = NULL,
  sampleprob = 0.15,
  seed = 123456789
)

Arguments

x: A continuous numeric vector.
n: (optional) The number of discretized classes.
method: (optional) The method of discretization, default is natural.
breakpoint: (optional) Break points for manually splitting data. When method is manual, breakpoint is required.
sampleprob: (optional) When the data size exceeds 3000, perform sampling for discretization, applicable only to natural breaks. Default is 0.15.
seed: (optional) Random seed number, default is 123456789.

Value

A discretized integer vector
