R: Plot of ERP curves.

erpplot

R Documentation

Plot of ERP curves.

Description

Wrapper for matplot (package graphics) to display ERP curves.

Usage

erpplot(dta, frames = NULL, ylim = NULL, ...)

Arguments

`dta`	Data frame containing the ERP curves: each column corresponds to a time frame and each row to a curve.
`frames`	Sequence of time frames. Default is NULL, in which case frames is just the sequence of intergers between one and the total number of frames.
`ylim`	Limits for the y-axis. Default is NULL (set into the function).
`...`	Graphical parameters (see par) and any further arguments of plot, typically plot.default, may also be supplied as arguments to this function. Hence, the high-level graphics control arguments described under par and the arguments to title may be supplied to this function.

Value

The function generates a plot, but does not return any other numerical outputs.
