Choroplethr

Choroplethr is a suite of R packages that facilitates mapping demographic statistics. The name "Choroplethr" comes from combining the words "choropleth map" and "R programming language". A choropleth is any map that shows regions, and expresses values for those regions with color.

Choroplethr is easy to use, has built-in support for mapping every country in the world and integrates with several open data sources, such as the US Census Bureau's American Community Survey (ACS).

Consulting

Choroplethr has led to a number of projects that leverage R, maps and open data sets. Past clients have come from the private sector as well as government agencies and non-profits. You can learn more about those projects, as well as how to get consulting help on your project, here.
