[R] Changing the origin in polar.plot in plotrix package

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
http://had.co.nz/ggplot2/coord_polar.html

although I'm still working on good axes etc for plots in polar coordinates.
