mapPolygon: Plot a polygon on a existing 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

latitude

latitudes of points to be plotted

density

as for polygon

angle

Details

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