Poisson Point Process on a Linear Network

Generates a realisation of the Poisson point process with specified intensity on the given linear network.

Keywords
spatial, datagen
Usage
rpoislpp(lambda, L, …, nsim=1, drop=TRUE)
Arguments
lambda

Intensity of the Poisson process. A single number, a function(x,y), a pixel image (object of class "im"), or a vector of numbers, a list of functions, or a list of images.

L

A linear network (object of class "linnet", see linnet). Can be omitted in some cases: see Details.

Arguments passed to rpoisppOnLines.

nsim

Number of simulated realisations to generate.

drop

Logical value indicating what to do when nsim=1. If drop=TRUE (the default), the result is a point pattern. If drop=FALSE, the result is a list with one entry which is a point pattern.

Details

This function uses rpoisppOnLines to generate the random points.

Argument L can be omitted, and defaults to as.linnet(lambda), when lambda is a function on a linear network (class "linfun") or a pixel image on a linear network ("linim").

Value

If nsim = 1 and drop=TRUE, a point pattern on the linear network, i.e.\ an object of class "lpp". Otherwise, a list of such point patterns.
