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

Many thanks in advance.
