[R] plotrix: reverse length scale

[Pep Serra]

Hi!

I wanted to know if there could be a way to reverse lengths in 
polar.plot or radial.plot.

As far as I am concerned, larger lengths imply lines or points further 
from the center of the circle and I want it the other way around: so if 
my length limits are from 0 to 2000 I want points with length near 2000 
to be closer to the circle center.

Thanx a lot,

pep
