Response surface plot
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
