halfSplit {AssocBin}

Halve at an observed point

Description

This function halves a bin under the restriction that splits can only occur at observation coordinates.

Usage

halfSplit(bin, margin = sample(c("x", "y"), 1))

Arguments

bin

a bin to be split with elements 'x', 'y', 'depth', 'bnds' (list with elements 'x' and 'y'), 'expn', 'n'

margin

string, one of 'x' or 'y'

Details

Given a bin and a margin, this function splits the bin so half the points are above the new split point and half are below.

Value

A list of two bins resulting from the split of 'bin' in half along the specified margin

bin <- list(x = 1:10, y = sample(1:10),
            bnds = list(x = c(0, 10), y = c(0, 10)),
            expn = 10, n = 10, depth = 0)
halfSplit(bin)
halfSplit(bin, margin = "y")
