image legend

I would like to add a legend to plots that I make with the image()
function in the form of a strip of colours to the right of the plot
annotated with their corresponding numerical values.
Is this possible?
Thank you,
Keith

A while back Jonathan Rougier posted a function called image.scale(),
which has worked nicely for me. Check it out here:
http://www.ens.gu.edu.au/robertk/R/help/99b/0483.html

I found it worked best floating in its own plot window (using layout() to
allocate most of the plotting area to the data plots and a tiny, thin,
section to an empty plot, which then contained the image.scale() legend).

Best,
Jake

I think you should definitely have a look at  filled.contour()
which is really a nice combination of  image() & contour()
and it has the ``colour strip scale'' to the right.

Get a first showoff from

    par(ask = TRUE)
    example(filled.contour)
