In osmnxr: Download, Model and Analyze 'OpenStreetMap' Street Networks

osmnxr 0.1.2

New ox_union() combines two or more osm_graph objects into one: node and edge tables are stacked, nodes sharing an osmid are merged and edges duplicated across graphs are dropped (dedupe_edges = FALSE keeps them). Attribute columns present in one graph but not another are filled with NA. Designed for multimodal networks — union a street graph with a hand-built layer (e.g. metro) whose transfer edges reference street-node osmids, then route across both (#1, requested by @talegari).

osmnxr 0.1.1

Fix installation on Windows (R-devel). The rextendr 0.5.0 Makevars templates ran an unnecessary install-time cargo run --bin document step that failed on Windows (os error 193 while running a build script). The extendr wrappers are pre-generated and shipped, so installation only needs cargo build --lib; the document step has been removed from Makevars.in / Makevars.win.in.

osmnxr 0.1.0

First public release of OSMnx for R.

ox_example() loads a small bundled real network (central Olinda, Brazil) so examples and vignettes show real analyses offline. The vignettes were reworked around real cases from Boeing (2025) and the OSMnx examples gallery: multi-city orientation entropy (Chicago/New Orleans/Rome), betweenness chokepoints, travel-time routing and isochrones, and amenity accessibility.
ox_orientation_entropy() and ox_plot_orientation() now accept either an osm_graph or a numeric vector of bearings.
ox_plot_figure_ground() draws figure-ground diagrams, and ox_example() now also bundles "manhattan" and "rome" networks for the new "Figure-ground diagrams" vignette (Boeing 2025, Fig. 3).
ox_simplify() now preserves traversability per direction, emitting bidirectional edges for two-way streets (fixes zero-valued routing/centrality on simplified graphs).
Download street networks from OpenStreetMap (ox_graph_from_place(), ox_graph_from_address(), ox_graph_from_point(), ox_graph_from_bbox()) via the Overpass API, returning the tidy sf-backed osm_graph object.
Geocoding with Nominatim (ox_geocode(), ox_geocode_to_sf()).
Rust compute core (via extendr): CSR graph, Dijkstra routing (ox_shortest_path(), ox_distances(), ox_nearest_nodes()) and metrics (ox_basic_stats(), ox_bearings(), ox_orientation_entropy()).
example_osm_graph() synthetic grid for offline examples and tests.
Configuration via ox_settings() and session caching with ox_clear_cache().
Topology cleanup (Rust core): ox_simplify() merges chains of interstitial degree-2 nodes into single edges; ox_consolidate_intersections() merges nearby nodes into one (via connected components); ox_nearest_edges() finds the closest edge to a point.
Advanced routing (Rust core): ox_k_shortest_paths() (Yen's algorithm), ox_distance_matrix() (many-to-many), and ox_isochrone() (reachable-area polygons via multi-source Dijkstra + concave hull).
Travel-time routing: ox_add_edge_speeds() and ox_add_edge_travel_times() add speed_kph / travel_time edge columns for time-weighted shortest paths and isochrones.
New vignette: "Routing and isochrones".
Network metrics (Rust core): ox_centrality() (betweenness via Brandes' algorithm, closeness) and ox_circuity() (street straightness). Circuity is now also reported by ox_basic_stats().
Interoperability: ox_as_sfnetwork(), ox_as_tidygraph() and ox_as_dodgr() hand the graph to the wider R network ecosystem.
Export and persistence: ox_to_geojson(), ox_to_maplibre() (style fragment), and ox_save_graphml() / ox_load_graphml() for a lossless round-trip (edge geometry stored as WKT), compatible with OSMnx / NetworkX / Gephi.
Feature downloads: ox_features_from_place() and ox_features_from_bbox() fetch POIs, buildings and amenities from OpenStreetMap as tidy sf points.
ox_plot_orientation() draws a polar rose plot of street bearings (ggplot2).
