HoldridgeToXY

CoordinatesToXY

Accepts various formats of input data; extracts ternary coordinates and
converts to X and Y coordinates.

internal

Plots ternary diagrams (simplex plots / Gibbs triangles) and
Holdridge life zone plots <doi:10.1126/science.105.2727.367> using the
standard graphics functions.
Allows custom annotation, interpolating, contouring and scaling of plotting
region.
Includes a 'Shiny' user interface for point-and-click ternary plotting.
An alternative to 'ggtern', which uses the 'ggplot2' family of plotting
functions.
