Add a Polygon to a Map

Plot a polygon on an existing map.

mapPolygon(longitude, latitude, density = NULL, angle = 45,
  border = NULL, col = NA, lty = par("lty"), ...,
  fillOddEven = FALSE)

`longitude`	longitudes of points to be plotted, or an object from which longitude and latitude can be inferred (e.g. a coastline file, or the return value from `mapLocator`), in which case the following two arguments are ignored.
`latitude`	latitudes of points to be plotted.
`density`	as for `polygon`.
`angle`	as for `polygon`.
`border`	as for `polygon`.
`col`	as for `polygon`.
`lty`	as for `polygon`.
`...`	as for `polygon`.
`fillOddEven`	as for `polygon`.

Adds a polygon to an existing map, by analogy to polygon. Used by mapImage.
