Load a bundled real-world example network

Loads a small, real street network shipped with the package (downloaded once from OpenStreetMap and simplified) so that examples and vignettes can show real analyses without network access.

Usage

ox_example(name = c("olinda", "manhattan", "rome"))

Arguments

name

Which network to load (all drivable, simplified): "olinda" (historic centre of Olinda, Pernambuco, Brazil), "manhattan" (a square mile of Midtown Manhattan, New York — a strong grid), or "rome" (the organic centro storico of Rome, Italy).

Value

An osm_graph.

Examples

g <- ox_example("olinda")
g
#> 
#> ── osm_graph ───────────────────────────────────────────────────────────────────
#> 498 nodes, 1191 edges
#> Network type: "unknown"
#> Simplified: FALSE
#> CRS: "WGS 84"
