dodgr_flows_aggregate() now has a pairwise parameter, to enable flows to
be aggregated only along paths connecting each pair of from and to
points. Thanks to @chinhqho via #229igraph::get.edgelist -> as_edgelist (#229) to suppress warnings
from igraph conversion functions.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 @agila5add_nodes_to_graph with "sc" networks (#217, thanks to @diegoteca)pairwise parameter added to dodgr_dists_categorical (#201)dodgr_dists_nearest() (#203)weight_streenet() function for wt_profile="bicycle" to return

where immediate usage is critical.dodgr_contract_graph returns the contracted graph only, instead of former
version which return list of graph and edge_map (the edge_map is cached
and re-loaded when needed for graph uncontraction).weight_streetnet renamed to turn_penaltyhampi data to remove factor columnsweight_streetnet function now returns edge times for all Open Street Map
networks extracted with the osmdata package.SC format data from osmdata::osmdata_sc()dodgr_times function to calculate journey times, including differential
speeds and penalties for intersections and traffic lights.dodgr::weighting_profiles data changed from single data.frame to list with
additional parameters determining speeds and time penalties for dodgr_times

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

option dodgr_dists(..., heap = "set") (It's 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
(Earth's 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.
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.
