Description Usage Arguments Examples
Convenience function for use with stat_voronoi
.
Uses geom_polygon
as the default geom and stat_voronoi
as the default stat.
To plot region borders instead of a choropleth map, use stat_voronoi
with geom="path"
,
or use fill=NA
with color="black"
.

mapping 
Set of aesthetic mappings created by 
data 
The data to be displayed in this layer. There are three options: If A A 
stat 
The statistical transformation to use on the data for this layer, as a string. 
position 
Position adjustment, either as a string, or the result of a call to a position adjustment function.

Other arguments passed on to 
na.rm 
If 
show.legend 
logical. Should this layer be included in the legends?
