[R] plotting data in non-orthogonal coords.

Hallo Andreas

There is probably no one who can give you some answer as you 
did provide almost no facts what you really did and what is wrong. 
You probably need to transform your coordinates to orthogonal 
and plot them as you wish. But you have to do it yourself. 

I had some data in polar coordinates some time ago and I did the 
same (see attached picture).
