ternary.legend: Plots a ternary legend

In trifield: Some basic facilities for ternary fields and plots

Description

Plots a legend giving the directions of the ternary axes and labels

Usage

ternary.legend(x0 = 0.2, y0 = 0.8, radius = 0.1, lab1 = "A", lab2 = "B", lab3 = "C", infl = 1.5, cex = 0.75, length = 0.05, ...)

Arguments

x0	x-coordinate of the center point
y0	y-coordinate of the center point
radius	how long to draw the axes
lab1	string giving first axis label
lab2	string giving second axis label
lab3	string giving third axis label
infl	space between axes and labels
cex	size of the labels
length	length of axis lines
...	additional parameters passed to arrows

Value

None

        sin(2 * pi * x[1]) +
        sin(3 * pi * x[2]) +
        sin(4 * pi * x[3])
z = ternary.apply(tg, f)
tf = ternary.field(tg, z)
plot(tf)
