ne_countries: Get natural earth world country polygons

In AndySouth/rnaturalearth: World Map Data from Natural Earth

Get natural earth world country polygons

Description

returns world country polygons at a specified scale, or points of tiny_countries

Usage

ne_countries(
  scale = 110L,
  type = "countries",
  continent = NULL,
  country = NULL,
  geounit = NULL,
  sovereignty = NULL,
  returnclass = c("sf", "sv")
)

Arguments

scale	The scale of map to return, one of '110', '50', '10' or 'small', 'medium', 'large'.
type	country type, one of 'countries', 'map_units', 'sovereignty', 'tiny_countries'
continent	a character vector of continent names to get countries from.
country	a character vector of country names.
geounit	a character vector of geounit names.
sovereignty	a character vector of sovereignty names.
returnclass	A string determining the spatial object to return. Either "sf" for for simple feature (from 'sf', the default) or "sv" for a 'SpatVector' (from 'terra').

Details

Note that the filename of the requested object will be returned if 'load = FALSE'.

If the data is to be loaded into memory ('load = TRUE'), the download will be handled using the GDAL virtual file system, allowing direct access to the data without writing it to disk.

Value

An object of class 'sf' for simple feature (from 'sf', the default) or 'SpatVector' (from 'terra').

ne_load, pre-downloaded data are available using ne_countries, ne_states. Other geographic data are available in the raster package : getData.

Examples

world <- ne_countries()
africa <- ne_countries(continent = "africa")
france <- ne_countries(country = "france")

plot(world$geometry)
plot(africa$geometry)
plot(france$geometry)

# get as SpatVector
world <- ne_countries(returnclass = "sv")
terra::plot(world)

tiny_countries <- ne_countries(type = "tiny_countries", scale = 50)
plot(tiny_countries)
