Two-Dimensional Density Estimation for Ternary Plots

panel.ternaryplot.density(x, y, z, subscripts, n = 100, region = TRUE,
  contour = FALSE, labels = isTRUE(contour), density_breaks = NULL, ...)

Arguments

x	Numeric vector
y	Numeric vector
z	Numeric vector
subscripts	See `lattice::panel.xyplot()`.
n	Number of grid points in each direction. Can be scalar or a length-2 integer vector.
region	Fill density or response estimates with a color gradient.
contour	Draw contour lines for density and response estimates.
labels	Label contour lines.
density_breaks	Breaks for the density plot if used (see `panel.ternaryplot.density()`).
...	Arguments that will be passed on to `lattice::panel.lines()`, `lattice::panel.polygon()`, and `lattice::panel.text()`.

Plots a layer inside a panel of a lattice plot.
