R help - Nov 2008 - radial.plot(plotrix) - plotting multiple polygons?

Is it possible to plot multiple polygons on radial.plot(plotrix)? The
new=FALSE argument (as used to add additional points or lines with the plot
function to an existing plot) doesn't appear to work. I would like to
overlay the outlines of multiple polygons of different colors on the same
radial plot.

Thanks,
Jeremy

Hi Jeremy,
You can do this by passing a matrix or data frame of values to 
radial.plot. Look at the last example on the help page for radial.plot 
and check the Details section.
