Low-level plot function which add tolerance ellipses to a high-level plot of a ternary diagram.
ternaryDiagEllipse(x, tolerance = c(0.9, 0.95, 0.975), locscatt = "MCD", ...)
Three-part composition. Object of class “matrix” or “data.frame”.
Determines the amount of observations with Mahalanobis distance larger than the drawn ellipse, scaled to one.
Method for estimating the mean and covariance.
