highest_concentration: Deprecated geohash hotspot search

In spatialrisk: Spatial Concentration and Radius-Based Risk Calculations

Deprecated geohash hotspot search

Description

'highest_concentration()' is deprecated. Use concentration_hotspot for fixed-radius hotspot detection in new analyses.

Usage

highest_concentration(
  df,
  value,
  lon = lon,
  lat = lat,
  lowerbound = NULL,
  radius = 200,
  grid_distance = 25,
  gh_precision = 6,
  display_progress = TRUE
)

Arguments

df	Deprecated. Data frame of point locations.
value	Deprecated. Column with values to aggregate.
lon	Deprecated. Longitude column.
lat	Deprecated. Latitude column.
lowerbound	Deprecated. Lower bound used by the legacy geohash search.
radius	Deprecated. Radius in meters.
grid_distance	Deprecated. Grid distance in meters.
gh_precision	Deprecated. Geohash precision used by the legacy search.
display_progress	Deprecated. Whether to show a progress bar.

Details

This legacy function used a geohash-based screening workflow. It is retained only for backward compatibility. The current high-level interface is concentration_hotspot, which documents the supported hotspot search methods and returns the current hotspot object structure.

Value

A legacy data frame with candidate hotspot coordinates and concentration values.
