plot_def: Default method of plotting the clustering results

In TengMCing/hotspotcluster: Spatiotemporal Clustering of Satellite Hot Spot Data

Default method of plotting the clustering results

Description

This function plots the clustering result spatially as a scatter plot.

Usage

plot_def(
  result,
  cluster = "all",
  hotspot = TRUE,
  noise = FALSE,
  ignition = TRUE,
  from = NULL,
  to = NULL,
  bg = NULL
)

Arguments

result	spotoroo object. A result of a call to hotspot_cluster().
cluster	Character/Integer. If "all", plot all clusters. If an integer vector is given, plot corresponding clusters.
hotspot	Logical. If TRUE, plot the hot spots.
noise	Logical. If TRUE, plot the noise points.
ignition	Logical. If TRUE, plot the ignition points.
from	OPTIONAL. Date/Datetime/Numeric. Start time. The data type needs to be the same as the provided observed time.
to	OPTIONAL. Date/Datetime/Numeric. End time. The data type needs to be the same as the provided observed time.
bg	OPTIONAL. ggplot object. If specified, plot onto this object.

Value

A ggplot object. The plot of the clustering results.

Examples

  # Time consuming functions (>5 seconds)


  # Get clustering results
  result <- hotspot_cluster(hotspots,
                          lon = "lon",
                          lat = "lat",
                          obsTime = "obsTime",
                          activeTime = 24,
                          adjDist = 3000,
                          minPts = 4,
                          minTime = 3,
                          ignitionCenter = "mean",
                          timeUnit = "h",
                          timeStep = 1)

  # Plot a subset of clusters
  plot_def(result, cluster = 1:3)

  # Plot all clusters
  plot_def(result, cluster = "all")
