trajectories (version 0.2-1)

density.list: Kernel estimate of intensity of trajectory pattern

Description

Estimating the intensity of a list of tracks.

Usage

# S3 method for 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

Value

an image of class "im".

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.

Examples

# NOT RUN {
X <- list()
for(i in 1:10){
  m <- matrix(c(0,10,0,10),nrow=2,byrow = TRUE)
  X[[i]] <- rTrack(bbox = m,transform = TRUE)
}
