diagnosticPlot {rMEA}

Plots the initial, middle and ending part of a MEA object

Description

This is typically useful to check if the motion energy time-series are good. The middle section is chosen randomly among possible middle sections.

Usage

diagnosticPlot(mea, width = 60, ...)

Arguments

mea

an object of class MEA (see function readMEA).

width

integer. The number of seconds to be plotted for each panel

...

further arguments passed to plot

Details

Motion energy time-series should always be visually inspected for possible artifacts. Periodic peaks or drops in time-series are indicators of e.g. key-frames or duplicated video-frames. For further information regarding the program MEA, please refer to the documentation available at http://www.psync.ch.

Examples

## read a single file
path_normal <- system.file("extdata/normal/200_01.txt", package = "rMEA")
mea_normal <- readMEA(path_normal, sampRate = 25, s1Col = 1, s2Col = 2,
                     s1Name = "Patient", s2Name = "Therapist", skip=1,
                     idOrder = c("id","session"), idSep="_")
## Visual inspection of the data
diagnosticPlot(mea_normal[[1]])
