An R package to hold and facilitate interaction with Natural Earth map data.
This package provides :
easy subsetting by countries and regions
functions to download other Natural Earth vector and raster data
a simple, reproducible and sustainable workflow from Natural Earth data to rnaturalearth enabling updating as new versions become available
clarification of differences in world maps classified by countries, sovereign states and map units
consistency with Natural Earth naming conventions so that rnaturalearth users can use Natural Earth documentation
data in sf or sv formats
The Natural Earth website structures vector data by scale, category and type. These determine the filenames of downloads. rnaturalearth uses this structure to facilitate download (like an API).
Install from CRAN :
or install the development version from GitHub using devtools.
Data to support much of the package functionality are stored in two data packages that you will be prompted to install when required if you do not do so here.
devtools::install_github("ropensci/rnaturalearthdata")
devtools::install_github("ropensci/rnaturalearthhires")Here using plot as a simple, quick way to plot maps. Maps could also be made with ggplot2, tmap or other options. All retrieval functions accept an argument returnclass = "sf" to return package sf (Simple Features) or returnclass = "sv" (SpatVector) objects.

There are a wealth of other data available at the Natural Earth website. rnaturalearth has functions to help with download of these data.
The data available are outlined in the two tables below and online here.
category cultural
category physical Specify the scale, category and type of the vector you want as in the examples below.
# lakes
lakes110 <- ne_download(scale = 110, type = "lakes", category = "physical")
plot(lakes110)
# rivers
rivers50 <- ne_download(
scale = 50,
type = "rivers_lake_centerlines",
category = "physical",
returnclass = "sf"
)
library(ggplot2)
library(sf)
ggplot(rivers50) +
geom_sf() +
theme_minimal()Script used to get data into the accompanying data packages.
Thanks to Lincoln Mullen for code structure inspiration from USAboundaries, Hadley Wickham for comments and prompting, Bob Rudis for answers to stackoverflow questions about downloading Natural Earth data into R. The Natural Earth team and Nathan Kelso for providing such a great resource.
