usmapdata {usmapdata} | R Documentation |
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.
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.
