HeadDirection-class: An S4 class used to get head direction histograms and...

In kevin-allen/relectro: Analysis of electrophysiological data

Description

The user creates positrack and spike train objects first. Then the user calls the different methods of this class with the spike train and positrack objects as arguments. It can get the vector length of the head direction histograms and do shuffling to know the threshold for significance.
