A tool for easily matching spatial data when you have a list of place/region names. You might have a data frame that came from a spreadsheet tracking some data by suburb or state. This package can convert it into a spatial data frame ready for plotting. The actual map data is provided by other packages (or your own code).
If you have a list of place/region names (for example as a column in a
data frame) and you’d like to turn that into spatial data,
{cartographer} can help. There are 2 steps:
{cartographer} using
register_map(), or load a package that already did that for you.add_geometry() to turn your ordinary data frame into a spatial
one.Cartographer will be most useful when you are working regularly with data about the same places. You can do the work once to curate your geospatial data, and thereafter you can use cartographer to quickly jump from place names to map data ready to analyse or visualise.
See vignette("cartographer") for examples, and {ggautomap} for some
handy ggplot helpers that pull map data using {cartographer}.
You can install cartographer like so:
# CRAN release
install.packages('cartographer')
# development version
install.packages('cartographer', repos = c('https://cidm-ph.r-universe.dev', 'https://cloud.r-project.org'))
Some packages provide data that works with {cartographer}:
{maps} - some dated example maps of the world and several countries.{rnaturalearth} - countries and states (where available).{nswgeo} - maps of New South Wales, Australia.Alternatively, you can register your own data using register_map()
(see vignette("registering_maps")).
