Given a list of geographic locations, such as cities, geomst calculates a minimum spanning tree between the locations. Plotting functionality also included.
latlon <- getLatLon(c('New York, New York', 'Boston, MA')) # Obtains latitude and longitude of locations
dist_mat <- getDistMat(latlon) # Gets distance matrix for locations
mst <- getMST(dist_mat) # Gets minimum spanning tree igraph object
graph_lines <- getGraphLines(mst, latlon) # Converts igraph object to something that can be plotted on a map
plotGraphLines(graph_lines) # Plots minimum spanning tree on a map
graphLines2Polyline(graph_lines) # Converts minimum spanning tree to a Polyline object that can be saved as a shapefile
