Hi Francois,
For one thing, you should be using radial.plot, as the angles are in 
radians, not degrees. However, your data shows up a couple of problems 
with radial.plot that I will fix. I'm currently fixing some minor (I 
hope) problems with plotrix v2.2-3 and this should turn up on CRAN in 
the next few days. I'll see if I can get radial.plot to produce the sort 
of plots you are seeking.

Thanks for finding the problem.
