An n-by-3 matrix of ternary forecasts.

A 2-by-3 matrix describing the transfromation for R^3 to R^2.

This is a utility function to calculate the y-coordinate of a point in barycentric coordinates.
It is unlikely that the user will want to use this function directly.

A suite of functions for visualising ternary probabilistic forecasts, as discussed in the paper by Jupp (2012) <doi:10.1098/rsta.2011.0350>.
