Dear List, I am trying to plot a similar graph to attached from minitab manual in R. I have a response Y and three components which systematically vary in their proportions. I have found in R methods/packages to plot ternary plots (eg. plotrix) but nothing which can extend it to response surface in 3-D. Any help appreciated, Tim Carnus [[alternative HTML version deleted]]
