plotAcc: Plots accelerometer data

In acc: Exploring Accelerometer Data

Description

Plots accelerometer data. This function receives summary object from function accsummary.

Usage

plotAcc(object,markbouts)

Arguments

object	An object returned from either the function accsummary.
markbouts	Whether to mark bouts. If markbout='TRUE' a bar along the time axis will indicate whether the epoch was counted as in bout or not. Default is false.

Value

A plot is returned.
