[R] triangle contour plots

Suppose I have three numbers p1, p2, p3 with 0 <= p1,p2,p3 <= 1 and p1+p2+p3=1,
and a function f=f(p1,p2,p3) = f(p1,p2,1-p1-p2).

How to draw a contour plot of f() on the p1+p2+p3=1 plane, that is, an equilateral triangle?

Functions triplot(), triangle.plot(), and ternaryplot() give only scatterplots, AFAICS
