chimaps: Chimaps of tarjectory pattern.

In trajectories: Classes and Methods for Trajectory Data

Chimaps of tarjectory pattern.

Description

Computes the chimaps, corresponding to a list of objects of class "Track". chimaps are based on the discrepancy between computed and expected intensity in a given location.

Usage

chimaps(X,timestamp,rank,...)

Arguments

X	A list of Track objects
timestamp	based on secs,mins,...
rank	a number between one and the length of corresponding time sequance which is created based on given timestamp.
...	passed to arguments of density.Track

Details

[estimated intensity - expected intensity] / sqrt(expected intensity).

Value

an image of class "im".

Examples

if (require(spatstat.geom)) {
 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)
 }
 chimaps(X, timestamp = "180 secs",rank = 2)
