  There is a floating.pie in the plotrix package, and a hidden floating.pie.asp function in the ape package. I agree that grid objects would be a more elegant way to implement these ... (The standard argument is that "thermometers" or mini-barplots would be a better way to view this information, but I agree that pie charts seem familiar to people.) I have the feeling that I've seen pie-charts-on-maps somewhere ... searching the R Graphics Gallery for "pie" also produces the "hexbin pie" plot (which doesn't use grid either ...)
