choroplethr: Functions to simplify the creation of choropleths (thematic maps) in R

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 four 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).
