Create and integrate maps in your R workflow!
This package allows various cartographic representations such as proportional symbols, choropleth, typology, flows or discontinuities maps. It also offers several features enhancing the graphic presentation of maps like cartographic palettes, layout elements (scale, north arrow, title...), labels, legends or access to some cartographic APIs.

The following script creates a map of symbols that are proportional to values of a first variable and colored to reflect the discretization of a second variable.
