choroplethr (version 1.3.0)
Functions to simplify the creation of choropleths (thematic
maps) in R.
Description
choroplethr simplifies the creation of choropleths in R. A
choropleth is a thematic map where geographic regions such as states are
colored according to some metric, such as which political party the state
voted for. choroplethr supports three levels of geographic resolution and
two types of scales. Common problems such as matching county data with map
data, choosing and labeling discrete scales and creating a clean background
are handled automatically. choroplethr provides native support for viewing
data from the US Census's American Community Survey (ACS).
