In rwoldford/treebinr: Data Reduction via Tree-based Binning

Description

Given a treebinr object, trimTo trims the tree to the desired size by removing the bins with the lowest measure value.

Usage

  bin@measure }, binMeasure, makePoint, updateBin, inputs = NULL)

Arguments

num	The number of points desired in the trimmed configuration
treebinr_obj	An object of class treebinr
getMeasure	A user supplied function to compute the measure to be compared between bins. By default, returns whatever value is in the measure slot of the bin object.
binMeasure	A user supplied function to compute the measure associated with each bin
makePoint	A user supplied function to turn the contents of a bin into a single point
inputs	A list containing additional input parameters required by user supplied functions
splitBin	A user supplied function for splitting a bin

Value

The return value is an object of class treebinr, which contains the following

points	A matrix containing the reduced point configuration
counts	A vector containing the number of points in each bin
bins	A list containing bin objects, which detail the contents of each bin
tree	An undirected graph object for the binning tree
