Plot lines on an existing map
mapLines(longitude, latitude, greatCircle = FALSE, ...)
longitude |
vector of 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 |
latitude |
vector of latitudes of points to be plotted. |
greatCircle |
a logical value indicating whether to render line segments as great circles. (Ignored.) |

optional arguments passed to |
Adds lines to an existing map, by analogy to lines.
