Description

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. bin.var is a synomym for binVariable, retained for backwards compatibility.

bin.var(...)

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.

...

arguments to be passed to binVariable.

Value

A factor.
