Filled contour plot showing labeled isolines?

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") -- David.

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 -- David Winsemius, MD West Hartford, CT
