Polygons with Holes for the Grammar of Graphics

Tools for working with polygons with holes in 'ggplot2', with a new 'geom' for drawing a 'polypath' applying the 'evenodd' or 'winding' rules.

ggpolypath

A ggplot2 geom for polygons with holes, called ‘geom_polypath’.

PLEASE NOTE: ggpolypath predates full support for polygonal path geoemtry in ggplot2, we advise use of the ggplot2 package directly rather than this package, please see https://www.tidyverse.org/blog/2019/06/ggplot2-3-2-0/.
