  returnclass = c("sp", "sf"))

Value

A Spatial object depending on the data (points, lines, polygons or raster).

Arguments

scale

scale of map to return, one of 110, 50, 10 or 'small', 'medium', 'large'

type

type of natural earth file one of 'countries', 'map_units', 'map_subunits', 'sovereignty', 'states' OR the portion of any natural earth vector url after the scale and before the . e.g. for 'ne_50m_urban_areas.zip' this would be 'urban_areas' OR the raster filename e.g. for 'MSR_50M.zip' this would be 'MSR_50M'

category

one of natural earth categories : 'cultural', 'physical', 'raster'

file_name

OPTIONAL name of file (excluding path) instead of natural earth attributes

Examples

if (FALSE) {
# download followed by load from tempdir() works in same R session
spdf_world <- ne_download( scale = 110, type = 'countries' )
spdf_world2 <-    ne_load( scale = 110, type = 'countries' )

# download followed by load from specified directory works between R sessions
spdf_world <- ne_download( scale = 110, type = 'countries', destdir = getwd() )
spdf_world2 <-    ne_load( scale = 110, type = 'countries', destdir = getwd() )

# for raster
# download & load
rst <- ne_download(scale = 50, type = 'OB_50M', category = 'raster', destdir = getwd())

# load after having downloaded
rst <- ne_load(scale = 50, type = 'OB_50M', category = 'raster', destdir = getwd())

# plot
library(raster)
plot(rst)
} # end dontrun
