Extract station-to-station distance matrix
A string containing the path to the SQLite3 database. If no directory specified, it is presumed to be in
City for which tripmat is to be aggregated
Distances are calculated by routing through the OpenStreetMap street network surrounding the bike stations, with the street network expanded by this amount to ensure all stations can be connected.
If FALSE, a square distance matrix of (num-stations, num_stations) is returned; if TRUE, a long-format matrix of (stn-from, stn-to, distance) is returned.
If FALSE, progress is displayed on screen
long = FALSE, a square matrix of numbers of trips between
each station, otherwise a long-form tibble with three columns of of
(start_station_id, end_station_id, distance)
Distance matrices returned from
bike_distamat use all stations
listed for a given system, while trip matrices extracted with
bike_tripmat will often have fewer stations because operational
station numbers commonly vary over time. The two matrices may be reconciled
