best.r {ForagingOrg}

Best-r index for foraging organization

Description

Calculates best-r indicator from a set of x and y coordinates. Best-r is defined as the best Pearson correlation (in absolute value) between the order in which targets are collected and their respective x and y coordinates (Ólafsdóttir et al., 2021; Woods et al., 2013).

Usage

best.r(x,y)

Arguments

x

A vector containing the x coordinates from the target locations.

y

A vector containing the y coordinates from the target locations.

Value

Returns the best-r as a numeric value.
