Dear all I am fighting with contour plot.
I have a continuous response and three factors. The formula argument in function contourplot() does not like the factors. What I got is really nonsense, loads of squares in the plot (exactly the same as what the help page says). I am wondering how I could get some beautiful curves instead of the ugly squares. I have really run out all the ideas I can find. Could anybody show me a way? Many thanks in advance. Huan This message and any attachments (the "message") is\ intended so ...
