Description

Produces a three dimensional, coloured plot from data provided as a binary, ordered predator-prey matrix. The matrix needs to have been analysed with the function analyse.single() in order for this function to work.

Usage

plotweb(cols, radii)

Arguments

cols

a list of colours, one per trophic level in the food web. Any colour name found is colours() or colors() is allowed. See colours() and colors()

radii
