Hi Thomas,
Greg has already given you most of the solutions. I was a bit surprised 
to find that if you include the negative values in the radial.lim 
argument, the polygon appears _and_ in the right place! I'll have to add 
this to the help page. Note that your labels may not be where you think 
they should be, as 0 degrees is east in your example. Maybe you want 
start=90?

I have thought about reprogramming the radial plot functions with an 
"add" argument, but haven't gotten around to it. I'll have a look and if 
I can do this without too much work, I'll let you know.

As far as 100 being prettier than 90, my experience is that I ain't 
gettin' any prettier as I get older.
