Thanks Jim.
That works well, thanks. Is there a way I can specify the range as it
seems to adjust automatically. Also I was hoping to plot multiple
datasets on the same chart but with different colours.
In the normal plot() I can do this with col = I was hoping to do
the same with points.co

Hi John,
One alternative would be to use ggplot2 with a polar coordinate system:
library(ggplot2)
qplot(mpg, wt, data=mtcars) + coord_polar()
qplot(mpg, wt, data=mtcars, ylim=c(3,4)) + coord_polar()
etc. You can see more examples of polar coordinates at

I am trying to draw a polar plot, which is easy enough to do in the
plotrix package through the polar.plot function.
However I would like to change the origin of the length vector. For
instance all my length values are between 75 and 85, so instead of
having the origin as 0 (the default) I'd like
