mapPolygon: Add a Polygon to a Map

Description

Plot a polygon on an existing map.

Usage

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

Arguments

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.

Details

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