Images as labels in a graph?

Question

I was wondering if there is a way to put images instead of numbers as X-axis labels in a scatter plot (or to that matter of fact, any plot) in R. I am currently using ggplot2 but any other library will be good enough. Any suggestions?

Answer 1

Look at the my.symbols function in the TeachingDemos package along with ms.image (same package) for one option using base graphics.
