Description

Bin a Numeric Variable

Usage

binVariable(
  x,
  bins = 4,
  method = c("intervals", "proportions", "natural"),
  labels = FALSE
)

Arguments

x	numeric variable to be binned.
bins	number of bins.
method	one of "intervals" for equal-width bins; "proportions" for equal-count bins; "natural" for cut points between bins to be determined by a k-means clustering.
labels	if FALSE, numeric labels will be used for the factor levels; if NULL, the cut points are used to define labels; otherwise a character vector of level names.

Details

Create a factor dissecting the range of a numeric variable into bins of equal width, (roughly) equal frequency, or at "natural" cut points. The cut function is used to create the factor.

Value

A factor.
