In the help page for filled.contour() it says that you have insert code
which adds to the plot via the 'plot.axes'. For example,
> a <- matrix(0, 10, 10)
> x <- runif(10)
> y <- runif(10)
> filled.contour(a, plot.axes = points(x, y))
However, if you do this, you'll notice the axes are gone. You need to
include explicit calls to axis() to solve this problem:
> filled.contour(a, plot.axes = { points(x, y); axis(1); axis(2) })
You can put a lot of code in the 'plot.axes' argument (using text(),
points(), lines(), etc.) and make really nice plots.
