Sorry, I guess I didn't make it clear. I mentioned it in the
subject of my
post, but not in the body. Is it possible to have a filled contour
plot
(showing the colors) with the isolines labeled?
Then levelplot _was_ (perhaps) the right answer.
levelplot(as.matrix(dfrm), contour=TRUE, labels=TRUE)

I was wrong about the name of lattice function that would do that
(although it is on ont the same help page.) It's contourplot rather
than levelplot. Assume you read this in and the data.frame name is
df:
require(lattice)
contourplot(as.matrix(df))
I have failed at getting more labels in the region where teh values
are higher. Here is one of my efforts:
contourplot(as.matrix(df[, 1:10]), at=c(0.1,0.2,0.3, 0.6, 0.9),
label.style="align")

I know
you can do this with Matlab. Argh!
It is fairly straightforward with lattice::levelplot. Provide some
sample data.
I tried creating a filled contour plot, then using par(new=T),
followed by
overlaying the contour plot on top. However, the placement of the
filled
contour plot and the contour plot do not align correctly. Any
suggestions
would be appreciated.
Thanks,
Jon
