bin.var(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.

Value

A factor.
