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

1

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".
