Spatial data plus the power of theggplot2 framework means easiermapping.
The package is available on CRAN, and can be installed usinginstall.packages("ggspatial"). The development version can beinstalled viaremotes.
install.packages("ggspatial")Or for the development version:
install.packages("remotes")# if remotes isn't installedremotes::install_github("paleolimbot/ggspatial")This package is a framework for interacting with spatial data usingggplot2 as a plotting backend. The package supportssf packageobjects,sp package objects, andraster package objects, andusesgeom_sf() andcoord_sf() to do most of the heavy lifting withrespect to coordinate transformation.
