Hello again,
look at the data provided by d, it's a list with:
- x : the 1st coordinate
- y : the 2nde coordinate
- z : a matrix of dimension 25 x 25 (the rectangles shown by image are
the representation of those 625 points, the contour
function uses interpolation.
See the n parameter in kde2d function, if you specify n=100, you won't
be able to see the rectangles, and that will be as pretty as you want.
Hope that clarify a bit.

Thanks, but this does not work correctly.
Contour lines with "contour" do not coincide
with those produced by "image". Also "image" plots
contour lines with right angles while "contour" plots
contour lines taking the diagonal between neighboring
points. All looks quite ugly.
If there are options to make them coincide I would
like to hear about them since I can't find them.
BTW: is it possible to change labeling og color
bar for filled.contour?

You might want to try ?image like in :
require(MASS)
x <- rnorm(50)
y <- rnorm(50)
d <- kde2d(x,y)
image(d,col=terrain.colors(50))
contour(d,add=T)
Hope this is what you are looking for.
Romain.

Hello,
I'd like to remove color bar from "filled.contour"
plot.
Is it possible and how?
I also want to overlay "contour" plot on
filled.contour
but due to scaling of the "filled.contour" to
account for the color bar, aspect ratio for
"contour"
is different from "filled.contour". Can this
problem
be solved?
Thanks,
Mark
