  destdir = tempdir(),
  file_name = NULL,
  returnclass = c("sp", "sf")
)

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'
destdir	folder to load files from, default=tempdir()

Examples

## Not run: 
# 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(terra)
plot(rst)
# end dontrun
