radial.plot(plotrix) - plotting multiple polygons?

Dear List, Dear Jim,

is it possible to draw multiple polygons with different line types? 
lty=c or line.lty=c do not work with radial.plot (in the matrix case) 
as well as add=TRUE.

Hi Stefan,
As this is the second request for multiple line characteristics this 
week, I suppose I should get to work on it. I'll see if I can solve it 
without breaking any code that is already written using radial.plot.

Jim
