Hi,

The trick is to use the argument plot.axes of filled.contour
There are examples of that in ?filled.contour

Besides the answers you already have, you might look at my "4D" graph 
example (with code) on the R Graphics Gallery:

I think it does exactly what you are asking, and therefore it might fit 
your needs with only slight code modification.

Dear All,

I have a question on overlaying a filled.contour (e.g. on soil properties data)
and contour (by elevation) in one graph. Both have the same z matrix dimension.
I'm able to overlay both graph, but the plots dimension did not overlap well
on the same plots. How can I have both filled.contour and contour on the same
graph? The commands that I have written are as follows:

filled.contour(0:15,0:10,t(matrix(Total.C,nrow=11,ncol=16)))
contour(0:15,0:10,as.matrix(elev),add=T)

Thanks for anay assistance.

Regards.
