[R] circular

[Greg Snow]

You may want to look at the density.circular and plot.density.circular functions in the circular package.

The pie slice idea is a bit tricky because the human eye tends to compare the areas of the slices rather than the distance from the center (and the area will be proportional to the distance squared).
