## Endler and Mielke (2005) tetrahedron colour space

### Description

Plots Endler and Mielke (2005) tetrahedron colour space for tetrachromatic animals.

### Usage

```
EMtetrahedron(x, y, z, s.col = "red", f.col = "black",
vnames = c("u","s","m","l"), type = "p",
radius = 0.01, add = F, xlab = "",
ylab = "", zlab = "", box = F, axes = F,
ylim = c(-0.75, 0.75), xlim = c(-0.75, 0.75),
zlim = c(-0.75, 0.75), aspect = T, vectors=FALSE, ...)
```
