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.
