R: Add Lines to a Map

mapLines {oce} | R Documentation

## Add Lines to a Map

### Description

Plot lines on an existing map

### Usage

    mapLines(longitude, latitude, greatCircle = FALSE, ...)

### Arguments

`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 `mapLocator`), in which case the following two arguments are ignored.
`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 `lines`.

### Details

Adds lines to an existing map, by analogy to `lines`.

    data(coastlineWorld)
    mapPlot(coastlineWorld, type='l',
            longitudelim=c(-80,10), latitudelim=c(0,120),
            projection="+proj=ortho +lon_0=-40")
    lon <- c(-63.5744, 0.1062)             # Halifax CA to London UK
