Plot concentration hotspot results — plot.hotspot • spatialrisk

Visualise objects returned by concentration_hotspot(). The default plot shows hotspot centres, fixed-radius buffers, and the contributing points. For terra-based results, diagnostic raster layers can also be plotted.

Usage

# S3 method for class 'hotspot'
plot(
  x,
  type = c("concentration", "focal", "rasterized", "updated_focal"),
  color1 = NULL,
  max.rad = 20,
  ...
)

Arguments

x: An object of class hotspot.
type: Plot type. "concentration" shows hotspot buffers and contributing points and works for all hotspot search methods. "focal", "rasterized", and "updated_focal" are diagnostic terra layers and are only available for terra-based results.
color1: Optional colour or colours for hotspot buffers and points. If NULL, colours are chosen with grDevices::hcl.colors().
max.rad: Maximum point radius passed to mapview::mapview(). Default is 20.
...: Additional arguments passed to mapview::mapview() for the contributing point layer when type = "concentration", or to the raster mapview call for diagnostic raster layers.

Value

A mapview object.

Details

The observed-points hotspot method does not create terra raster or focal objects. For observed-points results, use type = "concentration".
