However, when viewing it in a third-party KML viewer, not all the polygon features are displayed. Thus, LinearRing and Polygon objects are always simple because they do cannot intersect themselves, by definition. Single Placemarker. The function is used to create and write a KML file on the basis of a given Polygons object (a list of Polygon objects of SpatialPolygonsDataFrame class) for the usage in Google Earth and Google Maps. if not NULL the name as character string of the kml file to be written to working directory as "NAME.kml" ...tagged with click, control, accessibility.
