I would like to ask if it is possible to create ternary diagrams with contours. I want to plot a property that depends on a ternary mixture composition, so I think this would be the best way. I found a similar question in a past R-help list message but there was no answer.
It is possible. Just produce a suitable matrix of values, set parts outside the triangle to NA and call contour. I have done it several times.
