Ternary or Triangular Plots.
triplot plots in a triangle the values of three variables. Useful for mixtures
(chemistry etc.).
triplot(a, f, m, symb=2, grid=FALSE, ...)
a |
Vector of first variable. |
f |
Vector of second variable. |
m |
Vector of third variable. |
symb |
Symbol to be plotted |
grid |
Plot the grid: TRUE or FALSE |
... |
Additional parameters for |
The function tri is called for its side effect to produce a plot.
