v0.1.3

Major changes: - New functions dodgr_fundamental_cycles and dodgr_full_cycles - New function dodgr_sflines_to_poly to convert sf collections of LINESTRING object into corresponding enclosed POLYGON objects. - New function dodgr_to_sf creates full sf objects, extending dodgr_to_sfc - New function igraph_to_dodgr converts igraph objects into dodgr format - New function dodgr_uncontract_graph to convert from contracted back into original, uncontracted from, including any additional data appended on to contracted graph.

Minor changes: - Bug fix with vignette caused by updates to tinytex rendering of svg - Bug fix for dodgr_dists (heap = "set") with integer distances

v0.1.2

Major changes: - New function dodgr_to_igraph - weight_streetnet is now a method, with implementations for objects of classes .sf and .sc. - New function 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") (It’s slower than others, but good for sake of completeness).

Minor changes: - Various modifications that should result in notable speed gains - dodgr_streetnet now accepts polygonal bbox argument, and uses osmdata::trim_osmdata to trim resultant network to within that polygon (issue #50). - Extended examples for weight_streetnet and dodgr_flows_aggregateto include a non-OSM example fromstplanr::routes_fast` (issue #45).

v0.1.1

Major changes: - Crucial fix of previous typo that made all dodgr_dist calculations wrong (Earth’s radius is 6371, not 3671!) - thanks to @chrijo - weight_streetnet function now accepts data.frame objects defining wt_profile, enabling modification and direct re-submission of dodgr::weighting_profiles - weighting_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)

Minor changes: - Added Malcolm Morgan (@mem48; bug-finder extraordinare) as contributor - Bug fix with dodgr_paths and simple data.frames, thanks to James Smith. - Bug fix of former improper handling of one-way edges, thanks to @chrijo. - match_pts_to_graph has additional connected parameter to allow points to be matched only to largest connected component.

v0.1.0

Major changes: - New function 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.

Minor changes: - match_pts_to_graph now accepts Simple Features (sf) collections of sfc_POINT objects to be matched.

v0.0.3

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

v0.0.2

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).

v0.0.1

Initial CRAN release.
