mosaic: Create average waveform plots for each subject in a single, multiplot window

Description

mosaic generates multiple plots in a single window. Plots are average waveforms for each subject. Each plot shows all conditions present in the data frame.

Usage

mosaic(data, electrodes, cols = 5, rows = 5)

Arguments

data

A data frame in the format returned from load.data

electrodes

A single value or concatenation of several values (to be averaged) indicating which electrodes to include in generating the plot. At this time, if the raw data files imported using load.data) do not have a header, you must include a capital "V" in front of the number and enclose each electrode in quotes. (For example, electrodes = "V78", or electrodes = c("V78", "V76").)

cols

An integer defining the number of desired columns of plots. The default is 5.

rows

An integer defining the number of desired rows of plots. The default is 5.

Value

A single window containing multiple plots (1 per subject)

Details

The default values for columns and rows (i.e., 5 and 5) and higher are best suited to the graphical parameters specified in the code. At this time, graphical parameters (e.g., tick marks and labels) do not scale with the number of rows and colums. As this feature is not intended to produce manuscript-ready plots, the option to explore your data with any number of rows and columns is available, but fewer rows and columns will yield crowded plots.

Single electrodes can be passed to the package functions, or several electrodes can be provided (i.e., when using dense arrays) and those electrodes will be averaged together as a single electrode.

Examples

# Inspect average ERP waveforms for each subject
mosaic(ERPdata, electrodes = "V78", cols = 5, rows = 5)
