plotPlacer: Randomly place plots in arena

In metricTester: Test Metric and Null Model Statistical Performance

Description

Given a desired number of plots, the arena size, and the plot size, will attempt to place plots down in a non-overlapping fashion

Usage

plotPlacer(no.plots, arena.length, plot.length)

Arguments

no.plots	Number of plots to place
arena.length	Length of one side of arena
plot.length	Length of one side of desired plot.

Details

Places plots down in non-overlapping fashion according to parameters supplied. Because this would run indefinitely if unacceptable parameters were supplied, a conservative check is implemented to "ensure" the function does not get stuck. If unacceptable parameters are supplied, will return an arena and a smaller total sampling area will need to be defined.

Value

A matrix with the X & Y coordinates of the four corners of each plot placed
