load a Natural Earth vector that has already been downloaded to R using ne_download
returns loaded data as a spatial object.
ne_load(scale = 110, type = "countries", category = c("cultural",
"physical", "raster"), destdir = tempdir(), file_name = NULL,
returnclass = c("sp", "sf"))scale |
scale of map to return, one of |
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() |
file_name |
OPTIONAL name of file (excluding path) instead of natural earth attributes |
returnclass |
'sp' default or 'sf' for Simple Features |
A Spatial object depending on the data (points, lines, polygons or raster).
