plothot: Plots an object obtained with 'DiffHotspots_n_k'

In DRHotNet: Differential Risk Hotspots in a Linear Network

Plots an object obtained with DiffHotspots_n_k

Description

This function plots a set of differential risk hotspots located along a linear network. An extension of the hotspots (including the kth order neighbours of the segments of the hotspots) is also plotted

Usage

plothot(X, hotspots, order_extension = NULL, which.plot = NULL, eps_image = F)

Arguments

X	- A lpp object representing a marked point pattern lying on a road network (linnet object)
hotspots	- A set of differential risk hotspots obtained with the function DiffHotspots_n_k
order_extension	- A natural number indicating a neighbourhood order to be used for constructing an extension of the differential risk hotspots. The summary is also given for the segments forming this extension
which.plot	- A numeric vector indicating which differential risk hotspots to plot (according to the way they are ordered in hotspots)
eps_image	- If set to TRUE, an .eps image is generated. By default it is set to FALSE

Examples

library(DRHotNet)
library(spatstat.geom)
library(spatstat.linnet)
library(spdep)
library(raster)
rel_assault <- relpnet(X = chicago, 
lixel_length = 50, h = 50, mark = "marks", category_mark = "assault")
hotspots_assault <- drhot(X = chicago, rel_probs = rel_assault, 
k = 0.5, n = 4)
plothot(X = chicago, hotspots = hotspots_assault)
