weight_streetnet now raises a warning (instead of an error) in case the input sf object has mixed geometry types instead of only LINESTRING. The function filters only the geometries having LINESTRING type (#246, thanks to @agila5).dodgr_streetnet objects to data.frame, rather than append; thanks to @agila5 (#244).weight_streetnet; #245 thanks to @agila5dodgr_flows_aggregate() now has a pairwise parameter, to enable flows to be aggregated only along paths connecting each pair of from and to points.

former data.frame is now dodgr::weighting_profiles$weighting_profiles.write_dodgr_wt_profile writes full profile to local .json file for editing and subsequent use via weight_streetnet(wt_profile_file=<local_file_name.json>).dodgr_dists(), dodgr_paths(), and dodgr_flows() can no longer be used to automatically download street networks, thus former parameters wt_profile and expand have been removed; networks must be explicitly downloaded with dodgr_streetnet().dodgr_fundamental_cycles and dodgr_full_cyclesdodgr_sflines_to_poly to convert sf collections of LINESTRING object into corresponding enclosed POLYGON objects.dodgr_to_sf creates full sf objects, extending dodgr_to_sfcigraph_to_dodgr converts igraph objects into dodgr formatdodgr_uncontract_graph to convert from contracted back into original, uncontracted from, including any additional data appended on to contracted graph.tinytex rendering of svgdodgr_dists (heap = "set") with integer distancesdodgr_to_igraphweight_streetnet is now a method, with implementations for objects of classes .sf and .sc.weight_railway to weight a network for railway routing.dodgr_dists implements Dijkstra paths with std::set sorting through new option dodgr_dists(..., heap = "set") (Itâs slower than others, but good for sake of completeness).dodgr_streetnet now accepts polygonal bbox argument, and uses osmdata::trim_osmdata to trim resultant network to within that polygon (issue #50).weight_streetnet and dodgr_flows_aggregateto include a non-OSM example fromstplanr::routes_fast` (issue #45).dodgr_dist calculations wrong (Earthâs radius is 6371, not 3671!) - thanks to @chrijoweight_streetnet function now accepts data.frame objects defining wt_profile, enabling modification and direct re-submission of dodgr::weighting_profilesweighting_profiles$value modified to 0-1 scores rather than previous percentage values.weight_streetnet flags any highway types not present in nominated or submitted weighting profile.dodgr_paths now has additional pairwise parameter to enable paths only between matched pairs of from and to points (so returning n paths rather than n^2), thanks to @mem48.dodgr_to_sf deprecated to dodgr_to_sfc (#43)dodgr_paths and simple data.frames, thanks to James Smith.match_pts_to_graph has additional connected parameter to allow points to be matched only to largest connected component.dodgr_flowmap plots maps of flows. Currently only writes .png files, because large networks can not be effectively plotted on graphic devices.dodgr_flows has option to routes flows from a set of source origins to all points in a network, attenuated by distance from those origins.dodgr_to_sf converts a spatially-explicit dodgr graph into Simple Features (sf) format.match_pts_to_graph now accepts Simple Features (sf) collections of sfc_POINT objects to be matched.Tidy C++ code that flagged errors on CRAN solaris machine. Nothing else.
v0.0.2 Major changes:dodgr_paths, for returning explicit shortest path routes.dodgr_flows, for aggregting flows across a network from multiple origin and destination points.merge_directed_flows, to reduce aggregated directional flows to non-directional equivalent values useful for visualisation.weight_streetnet now accepts arbitrary sf-formatted networks via specification of custom weighting profiles, along with highway type and ID columns in data.frame.dodgr_dists inherit the names of routing points (from and to parameters).Initial CRAN release.
