dodgr_dists_categoricaldodgr_streetnet, thanks to @LeshunXu (#174)| -> ||)Minor changes:
dists_categorical(proportions_only = TRUE)
to ensure all edge types are aggregated (final type was previously not
aggregated).Major changes:
dodgr_dists_categorical function + accompanying
vignetteMajor changes:

Minor changes:
dodgr_flows_disperse() thanks for
@romainFrkeep_cols param in weight_streetnet();
#140 thanks to @agila5integer not
numericMinor changes: - UBSAN Bug fix
Major changes: - Added new dodgr_centrality function,
and associated helper functions. - Added new dodgr_flows_si
function - Added new parameter norm_sums to
dodgr_flows_aggregate - merge_directed_flows
renamed to merge_directed_graph, with added option of
specifying columns to merge. - Added new pairwise parameter
to dodgr_distances; see issue #127 - Added new function
dodgr_insert_vertex to add new vertices to graph; see #40 -
Removed “radix” heap option
Minor changes: - switch off examples that caused previous CRAN
failures - fix bug in dodgr_dists when number of from
points >> number of to points - fix bug in
weight_streetnet.sc that prevented keep_cols
from working
Major changes: - Remove benchmark vignette
Minor changes: - bug fixes in dodgr_paths, thanks to
@agila5
Major changes: - Add dodgr_isochrones,
dodgr_isodistances, and dodgr_isoverts
functions - Considerable speed-ups for
dodgr_flows_aggregate and
dodgr_flows_disperse
Minor changes: - dodgr_flows_disperse allows
k to be a vector, with different coefficients for each
from point. - Add “highway:pedestrian” to weighting
profiles - weight_streetnet for sc objects
automatically adds component column - bug fix in
weight_streetnet.sc(..., wt_profile = 1) - bug fix in
dodgr_full_cycles for SC class objects
Major changes: - Lots of intermediate processes now executed and
cached as background processes (via callr package). - new
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).
Minor changes: - ‘turn_angle’ parameter of
weight_streetnet renamed to turn_penalty -
Test coverage now complete (100%) * Update internal hampi
data to remove factor columns - Fix some bugs in max speed calculations
for weight_streetnet * Fix bug with polygonal bbox in
dodgr_streetnet()
Major changes: * New vignette on street networks and time-based
routing - weight_streetnet function now returns edge times
for all Open Street Map networks extracted with the osmdata
package. - weight_streetnet now accepts SC format data from
osmdata::osmdata_sc() - New 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. - New
function 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().
Minor changes: - Bug fix with dodgr_to_igraph to create proper weighted igraph - Add “footway” to weighting_profiles
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
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).
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.
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.
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.
