colourvision (version 2.1.0)

CTTKhexagon3D: Chittka (1992) colour space for tetrachromatic animals.

Description

Plots a hexagonal trapezohedron representing Chittka (1992) colour space for tetrachromatic animals (Thery and Casas, 2002).

Usage

CTTKhexagon3D(x, y, z, s.col = "red", f.col = "black",
              vnames = c("E1","E2","E3","E4"), type = "p",
              radius = 0.01, add = F, xlab = "", ylab = "", zlab = "",
              box = F, axes = F, ylim = c(-1, 1), xlim = c(-1, 1),
              zlim = c(-1,1), aspect = T, vectors=F, ...)
