Voronoi diagrams are tools for the visualization of georeferenced data : nearest neighbor regions are determined for a given set of points. in this tutorial, we use the R package “deldir” to analyze and visualize point patterns with voronoi diagrams. The data and R code to reproduce the examples is available on my github.
