R help - Jan 2003 - contour plot

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

When you have numerical "x" variables, rather than factors, you can
make
sensible contour plot.  Short of that, nothing in this world will give you
"beautiful curves".

What does the help page say ? What versions of R and lattice are you using ?
