Getting the Velocity AutoCorrelation

Description

The VeAutoCor function automatically compute the changes in both speed and direction across several sequantial time intervals.

Usage

getVACtable(object)

Arguments

object

CellMig class object, which is a list of data frames resulted from the PreProcessing.

Value

A data frame, which contains six rows: "Cell Number", "Velocity AutoCorrelation (lag=1)", "2nd normalized Velocity AutoCorrelation", "Intercept of VA quadratic model", "Mean Velocity AutoCorrelation (all lags)", "Mean |Acceleration|" and "Average Speed".
