View source: R/all_functions_v8.R

Description

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

Usage

1
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".
