In trajectories: Classes and Methods for Trajectory Data

Kernel estimate of intensity of trajectory pattern

Description

Estimating the intensity of a list of tracks.

Usage

## S3 method for class 'list'
density(x, timestamp,...)

Arguments

x	a list of "Track" objects, an object of class "Tracks" or "TracksCollection"
timestamp	based on secs, mins, ...
...	passed to arguments of density.ppp

Details

This estimate the average intensity function of moving objects over time. Bandwidth selection methods such as bw.diggle, bw.scott and bw.ppl can be passed to this density.list.

Value

an image of class "im".
