Hi,
Exactly the matrix transformation is the one that pasted in my first
mail. That is here:
new_point <- function(x1, x2, y1, y2, grad=1.73206){
b1 <- y1-(grad*x1)
b2 <- y2-(-grad*x2)
M <- matrix(c(grad, -grad, -1,-1), ncol=2)
intercepts <- as.matrix(c(b1,b

Your question makes absolutely no sense at all. See inline below.

Hello R users,
I am trying to make a baricentric diagram like the ternary plot, but with 4

edges are A, B, C, D. If value of A=B=C=D, then the point should be at the
