Hi,

I am interested in representing graphically
response surfaces (=contours) for
mixture designs. When I have for example 3 components, I can
represent the contours nicely in a equilateral triangle.

I can write a S-Plus function for doing this, but
I am curious if anybody else already spent some time
on this issue. StatLib offers nothing (to my knowledge).

Thanks in advance!

Marcel
