plothot {DRHotNet}

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
