usmapdata: Mapping Data for usmap Package
Description
It is usually difficult or inconvenient to create US maps that include both Alaska and Hawaii in a convenient spot. All map data frames produced by this package use the US National Atlas Equal Area projection.
Map data frames
Alaska and Hawaii have been manually moved to a new location so that
their new coordinates place them to the bottom-left corner of
the map. These maps can be accessed by using the us_map function.
The function provides the ability to retrieve maps with either
state borders or county borders using the regions parameter
for convenience.
States (or counties) can be included such that all other states (or counties)
are excluded using the include parameter.
