splitTrack

Methods for analyzing (cell) motion in two or three dimensions.
Available measures include displacement, confinement ratio, autocorrelation,
straightness, turning angle, and fractal dimension. Measures can be applied to entire tracks,
steps, or subtracks with varying length. While the methodology has been developed for
cell trajectory analysis, it is applicable to anything that moves including animals,
people, or vehicles.
Some of the methodology implemented in this packages was described by:
Beauchemin, Dixit, and Perelson (2007) <doi:10.4049/jimmunol.178.9.5505>,

splitTrack function

<dl><dt>x</dt>
<dd>the input track (a data frame or a matrix).</dd>
<dt>positions</dt>
<dd>a vector of positive integers, given in ascending order.</dd>
<dt>id</dt>
<dd>a string used to identify the resulting tracks; for instance,
if <code>id="X"</code>, then the resulting tracks are named X_1, X_2 and so forth.
Otherwise, they are simply labelled with integer numbers.</dd>
<dt>min.length</dt>
<dd>nonnegative integer. Resulting tracks that have fewer positions than
the value of this parameter are dropped.</dd></dl>
