Paint tiles on ternary plot

Description

Function to fill a ternary plot with coloured tiles. Useful in combination with TernaryPointValues and TernaryContour.

Usage

TernaryTiles(
  x,
  y,
  down,
  resolution,
  col,
  direction = getOption("ternDirection", 1L)
)

Arguments

x, y	Numeric vectors specifying x and y coordinates of centres of each triangle.
down	Logical vector specifying TRUE if each triangle should point down (or right), FALSE otherwise.
resolution	The number of triangles whose base should lie on the longest axis of the triangle. Higher numbers will result in smaller subdivisions and smoother colour gradients, but at a computational cost.
col	Vector specifying the colour with which to fill each triangle.
direction	(optional) Integer specifying the direction that the current ternary plot should point: 1, up; 2, right; 3, down; 4, left.
