erpR (version 0.2.0)

erp.add: add an ERP waveform to a plot

Description

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

Usage

erp.add(el, startmsec=-200, endmsec=1200, interval=c(startmsec, endmsec), 
smo = NULL, col = "black", lty = 1, lwd = 1, ...)

Arguments

el

the electrode to be plotted.

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.

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.
