Hi,
I used similar things to Chemical Mixture Modelling. ( Scheffe model)
I make the function below.
Cleber
+
trimage <- function(f){
x = y = seq( 1, 0, l=181 )
t1 = length(x)
im = aux = numeric(0)
for( i in seq( 1, t1, by = 2 ) ){
#idx

The usual conto
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 s
