Description

Layers a ggplot2 map of the world over the current ggplot2 object.

Usage

1
2
draw_world(g = ggplot() + theme_bw() + xlab("") + ylab(""),
  inc_border = TRUE)

Arguments

g

initial ggplot object

inc_border

flag indicating whether a map border should be drawn or not; see details.

Details

This function uses ggplot2::map_data in order to create a world map. Since, by default, this creates lines crossing the world at the (-180,180) longitude boundary, function .homogenise_maps is used to split the polygons at this boundary into two. If inc_border is TRUE, then a border is drawn around the lon-lat space; this option is most useful for projections that do not yield rectangular plots (e.g., the sinusoidal global projection).
