OK, I used the paper "Integrating grid Graphics Output with Base Graphics Output" by Paul Murrell (R News) which has an example of implementing pie maps and made up a function from that. It looks actually very nice!
One thing I couldn't figure out is if I can make pie charts transparent, so that another chart below it would show through. One more: Generally, how can I find out what values for the parameters of gpar() are available?
