Tidy C++ code that flagged errors on CRAN solaris machine. Nothing else.


Major changes: - New function, dodgr_paths, for returning explicit shortest path routes. - New function, dodgr_flows, for aggregting flows across a network from multiple origin and destination points. - New function, merge_directed_flows, to reduce aggregated directional flows to non-directional equivalent values useful for visualisation.

Minor changes: - weight_streetnet now accepts arbitrary sf-formatted networks via specification of custom weighting profiles, along with highway type and ID columns in data.frame. - Distance matrices from dodgr_dists inherit the names of routing points (from and to parameters).


Initial CRAN release.
