Hi Charles,
You don't need as.layer.
levelplot(z ~ x*y,grid2) + contourplot(z ~ x*y,grid1)
is enough.

Pascal

Dear all,
Just to inform that I have solved my problem in a very elegant way, thanks
to the layer approach given by package latticeExtra.
After loading my grids like before:
x-1:10
y-1:10
grid1-expand.grid(x=x,y=y)
grid2-expand.grid(x=x,y=y)
z1-grid1$x^2 + grid1$y^2
z2-2*grid2$x^2 - grid2$y^2
grid1$z-z1
grid2$z-z2
I just need to do:
levelplot(z ~ x*y,grid2) + as.layer(contourplot(z ~ x*y,grid1));
The result is a beautiful plot with a contourplot over a levelplot. There
are some examples of overlay of trellis plots in the manual of
latticeExtra: http://latticeextra.r-forge.r-project.org/
Thank you for your attention,
Best,
Charles

Dear all,
Does anyone know a way to overlay a contourplot and a levelplot of
different datasets, both datasets with the same dimension?
Let's say I have 2 10x10 grids, like those below:
library(lattice)
x-1:10
y-1:10
grid1-expand.grid(x=x,y=y)
grid2-expand.grid(x=x,y=y)
z1-grid1$x^2 + grid1$y^2
z2-2*grid2$x^2 - grid2$y^2
grid1$z-z1
grid2$z-z2
I would like to plot z1 and z2 in the same plot: z1 as a contourline and
z2 as a levelplot. I tried to do this in two ways, without success:
plot.new();
contourplot(z ~ x*y,grid1)
par(new=T)
levelplot(z ~ x*y,grid2)
and
levelplot(z ~ x*y,grid1,region=FALSE,contour=TRUE)
par(new=T)
levelplot(z ~ x*y,grid2,region=TRUE,contour=FALSE)
Any clue?
Thank you very much for your time and any help!
Charles
