selectTracks: Select Tracks by Measure Values

In MotilityLab: Quantitative Analysis of Motion

Description

Given a tracks object, extract a subset based on upper and lower bounds of a certain measure. For instance, extract all tracks with a certain minimum length.

Usage

selectTracks(x, measure, lower, upper)

Arguments

x	the input tracks.
measure	measure on which the selection is based (see TrackMeasures).
lower	specifies the lower bound (inclusive) of the allowable measure.
upper	specifies the upper bound (inclusive) of the allowable measure.

Examples

## Slower half of T cells
slow.tcells <- selectTracks( TCells, speed, -Inf, median( sapply(TCells,speed) ) )
