This geom makes it easy to construct regular polygons (polygons where all sides and angles are equal) by specifying the number of sides, position, and size. The polygons are always rotated so that they "rest" on a flat side, but this can be changed with the angle aesthetic. The size is based on the radius of their circumcircle and is thus not proportional to their area.

The geometric object to use display the data
Position adjustment, either as a string, or the result of a call to a position adjustment function.

Other arguments passed on to
The statistical transformation to use on the data for this layer, as a string.
