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 |
