  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'

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)
