Description

Applies the fly categorical colour vision model of Troje (1993)

Usage

categorical(vismodeldata)

Arguments

vismodeldata

(required) quantum catch color data. Can be either the result from vismodel or independently calculated data (in the form of a data frame with four columns representing a tetrachromatic dipteran viewer).

Value

Object of class colspace consisting of the following columns:

R7p, R7y, R8p, R8y: the quantum catch data used to calculate the remaining variables.

x, y: cartesian coordinates in the categorical colour space.

r.vec: the r vector (saturation, distance from the center).

category: fly-colour category. One of p-y-, p-y+, p+y-, p+y+.
