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.
