yf {ternvis} | R Documentation |
y coordinate of a ternary forecast in barycentric coordinates
Description
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.
Usage
yf(p = cbind(1, 1, 1)/3, M = tsetup()$M32)
Arguments
p |
An n-by-3 matrix of ternary forecasts. |
M |
A 2-by-3 matrix describing the transfromation for R^3 to R^2. |
Value
An n-by-1 array of y-values for use in plotting.
