erp.add: add an ERP waveform to a plot

In erpR: Event-Related Potentials (ERP) Analysis, Graphics and Utility Functions

Description

Add a waveform to a ERP plot created with erp, erp.t, or butterfly functions.

Usage

erp.add(erpdf, electrode, startmsec=NULL, endmsec=NULL, interval=NULL, 
smo = NULL, col = "black", lty = 1, lwd = 1, ...)

Arguments

erpdf	a data.frame with timepoints in row and electrodes in columns.
electrode	character indicating the electrode to plot.
startmsec	the start time (in ms) of the ERP vector.
endmsec	the end time (in ms) of the ERP vector.
smo	the smoothing parameter to apply (see smooth.spline). Default is NULL and no smoothing is applied.
interval	a vector with a pair of values indicating the interval (in milliseconds) to be plotted. Default is from startmsec to endmsec.
col	the color of the waveform.
lty	line type of the waveform .
lwd	line width of the waveform.
...	further parameters passed to lines

Value

The specified waveform is added to an existing plot.
