\title{Download data from Natural Earth and (optionally) read into R}
\usage{
ne_download(
  scale = 110,
  type = "countries",
  category = c("cultural", "physical", "raster"),
  destdir = tempdir(),
  load = TRUE,
  returnclass = c("sf", "sv")
)
}
\arguments{
\item{scale}{The scale of map to return, one of `110`, `50`, `10` or `small`,
`medium`, `large`.}

\item{type}{type of natural earth file to download 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'. See Details. OR the
raster filename e.g. for 'MSR_50M.zip' this would be 'MSR_50M'}

\item{category}{one of natural earth categories : 'cultural', 'physical',
'raster'}

\item{destdir}{where to save files, defaults to \code{tempdir()},
\code{getwd()} is also possible.}

\item{load}{`TRUE` load the spatial object into R, `FALSE` return the
filename of the downloaded object.}

\item{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`).}
}
\value{
An object of class `sf` for simple feature (from `sf`, the default)
or `SpatVector` (from `terra`).
}
\description{
returns downloaded data as a spatial object or the filename if
\code{load=FALSE}. if \code{destdir} is specified the data can be reloaded in
a later R session using \code{\link{ne_load}} with the same arguments.
}
\details{
Note that the filename of the requested object will be returned if
`load = FALSE`.
}
\examples{
\dontrun{
spdf_world <- ne_download(scale = 110, type = "countries")

plot(spdf_world)
plot(ne_download(type = "populated_places"))

# reloading from the saved file in the same session with same arguments

spdf_world2 <- ne_load(scale = 110, type = "countries")

# download followed by load from specified directory will work across sessions
spdf_world <- ne_download(scale = 110, type = "countries", destdir = getwd())
spdf_world2 <- ne_load(scale = 110, type = "countries", destdir = getwd())

# for raster, here an example with Manual Shaded Relief (MSR) download & load

rst <- ne_download(scale = 50, type = "MSR_50M", category = "raster", destdir = getwd())

# load after having downloaded
rst <- ne_load(
  scale = 50, type = "MSR_50M", category = "raster", destdir =
    getwd()
)

# plot
library(terra)
terra::plot(rst)
# end dontrun
}

\seealso{
\code{\link{ne_load}}, pre-downloaded data are available using
  \code{\link{ne_countries}}, \code{\link{ne_states}}. Other geographic data
  are available in the raster package : \code{\link[raster]{getData}}.
