With sweave, you need to explicitly print() the output of ggplot2 and
lattice plots.

qplot does (?) what I was looking for!
At least it plots what I want to plot in the interactive modus.
However, it seems not to work with Sweave.

Thanks Hadley. As I suspected, but ggplot2 is so very clever that I
thought it was worth asking :)

Hi Hadley,
I read the original question as being about irregularly spaced data.
The above method doesn't seem to for me in such a case but perhaps I'm
constructing my example incorr

Hi,
Would like to make an image
however the values in z are not on an uniform grid.
Have a dataset with
length(x) == length(y) == length(z)
x[1],y[1] gives the position of z[1]
and would like to encode value of z by a color.
looking for something like
plot(x,y, col = z)
where col for z is cleve
