In lboxell/geomst: Obtains minimum spanning tree from vector of geographic locations

geomst

Description

Given a list of geographic locations, such as cities, geomst calculates a minimum spanning tree between the locations. Plotting functionality also included.

Example

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
