ternary.grid (Package: trifield) :

The function builds a rectangular lattice of points bounded by an equilateral triangle with unit altitude. It can be used with ternary.apply and ternary.field to create a surface of values for plotting.

trifield-package (Package: trifield) :

The package can project between unity-summed ternary vectors and binary vectors. An "apply" function is provided to apply a function over a ternary field, as is a function for constructing ternary grids. Some rudimentary plotting functions are also provided. This is quick and dirty research code I needed in the course of writing a manuscript. Take it as such.

triaxes (Package: trifield) :

Draws lines separating adjacent halves of the equilateral triangle with unit altitude

plot.trifield (Package: trifield) :

A simple wrapper around image and contour for plotting ternary fields

ternary.apply (Package: trifield) :

Given 1) a ternary grid and 2) a function that takes a ternary value as its first argument, this function returns a vector formed by applying the function to each point in the grid.
