Spatial data plus the power of the
ggplot2 framework means easier mapping.
The package is available on CRAN, and can be installed using
install.packages("ggspatial"). The development version can be installed via remotes.
Or for the development version:
install.packages("remotes") # if remotes isn't installed remotes::install_github("paleolimbot/ggspatial")
This package is a framework for interacting with spatial data using ggplot2 as a plotting backend. The package supports sf package objects, sp package objects, and raster package objects, and uses
coord_sf() to do most of the heavy lifting with respect to coordinate transformation.
