to ensure all edge types are aggregated (final type was previously not
aggregated).dodgr_dists_categorical function + accompanying
vignetteweight_streetnet now includes turn restrictions when
input data are extracted with dodgr_streetnet_sc (#136

and dodgr_isoverts functionsdodgr_flows_aggregate and
dodgr_flows_dispersedodgr_flows_disperse allows k to be a
vector, with different coefficients for each from

automatically adds component columnweight_streetnet.sc(..., wt_profile = 1)dodgr_full_cycles for SC class
objectscallr package).dodgr_cache_off function added to suppress primary
caching, for cases 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 function; 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

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")
(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.
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
