Load a TPS incident dataset for the statistical-physics suite — morie_tps_load_tps

Portable dataset bridge: uses a local project export via morie_tps_load_dataset() when one exists, otherwise fetches the category live from the public Toronto Police Service ArcGIS portal via morie_fetch_tps() (cached under cache_dir). No private infrastructure is involved, so results reproduce on any machine.

Usage

morie_tps_load_tps_dataset(
  category,
  nrows = NULL,
  cache_dir = file.path(tempdir(), "morie", "tps")
)

Arguments

category: TPS category name (see morie_tps_layer_urls()).
nrows: Optional row cap applied after load.
cache_dir: Cache directory for the live fetch; defaults to a session temporary directory.

Value

A data.frame of incidents.

Examples

# \donttest{
try(head(morie_tps_load_tps_dataset("Homicides", nrows = 100)))
#> morie_tps: no local TPS cache for 'Homicides'; using the bundled sample from rmorie. Fetch the full export with morie_tps_fetch_category().
