netmap {netmap}

netmap: Plot network and igraph objects on a sf map using ggplot2

Description

The netmap package extends the ggnetwork package by providing functions to plot networks, with vertices usually representing objects with a spatial attribute (cities, regions, countries, users with location data attached etc.) on a map, provided by a sf object (which in turn is able to represent more or less all spatial data available). Networks and maps need not have the same set of elements: if they don't, only the intersection will be represented.

netmap functions

The main function is ggnetmap, which produces a data.frame that is then used as data within ggplot2 calls. For those wishing to use the plot.network or the plot.igraph function to plot the network (without overlaying it on an sf object), both a custom layout function, network.layout.extract_coordinates, and a wrapper that provides convenient manipulation of network and sf objects, netmap_plot, are available.
