assign.optbin {optbin}

Bin Assignment

Description

assign.optbin returns an object with the same shape as the input data and values replaced by bin numbers.

Usage

assign.optbin(x, binspec, extend.upper=FALSE, by.value=FALSE)

Arguments

x

numeric data to assign

binspec

an optimal binning partition

extend.upper

if true then any value in x above the last bin is assigned to that bin, otherwise its bin is set to NA

by.value

if true then return average value for bin instead of bin numbers

Details

Replaces the values in a copy of the input data by the bin number it belongs to, or by the bin average value with by.value. The lowest bin always extends to -Inf. The extend.upper argument can open the last bin to +Inf if true. Use this function to get in-place bin assignments for the unsorted data that was passed to optbin.

Value

An object of the same shape as the data.
