R help - Oct 2010 - contour on a simplex

Hello,

anyone knows if there is a way in R to draw contour on a simplex based on a
function f(x,y,z)  with domain (x+y+z = 1)?

Thank you!

Check out this post on R-help from February, and look carefully at the
solution of Walmes Zeviani - I believe it's close to what you're
requesting:
