EMline: Endler and Mielke (2005) 1-D colour space

In colourvision: Colour Vision Models

Description

Plots a colour space for dichromatic Endler and Mielke (2005) colour vision model.

Usage

EMline(x,y=rep(0, length(x)), type="length",
         vnames=c("E1","E2"), 
         ylim="auto", xlim="auto",
         ann=FALSE, axes = FALSE, ...)

Arguments

x	x-coordinate
y	y-coordinate
type	Whether the colour space should be built with a fixed vector length, or a fixed edge length (distance between vertices).
vnames	Vector names
ylim	see plot function.
xlim	see plot function.
ann	see par function.
axes	see plot.default function.
...	Other arguments passed to plot.

Details

The original model is available for tetrachromatic animals only. Colour space is built either with a vector length = 0.75 or a edge length = sqrt(3/2), to match the tetrahedron proposed by Endler and Mielke (2005).
