erp_image: Plot ERP images

In neuroconductor-devel-releases/eegUtils: A collection of utilities for EEG analysis

Description

Plot an ERP image from a single electrode. Smooths over a series of trials in order to make across-trial patterns more apparent.

Usage

erp_image(data, ...)

## Default S3 method:
erp_image(data, electrode = "Cz", smoothing = 10,
  clim = NULL, interpolate = FALSE, ...)

## S3 method for class 'eeg_epochs'
erp_image(data, electrode = "Cz", smoothing = 10,
  clim = NULL, interpolate = FALSE, ...)

## S3 method for class 'eeg_ICA'
erp_image(data, component = "Comp1", smoothing = 10,
  clim = NULL, interpolate = FALSE, ...)

Arguments

data	Data frame to be plotted. Requires an amplitude column.
...	Other arguments passed to the method.
electrode	electrode at which to generate an ERP image.
smoothing	Number of trials to smooth over when generating image
clim	Character vector of min and max values of plotting colour range. e.g. c(-5,5). Defaults to min and max.
interpolate	Perform interpolation to produce smoother looking plots. Defaults to FALSE.
component	eeg_ICA component to plot

Methods (by class)

• default: Default function operates on normal data frames

• eeg_epochs: Create an erp_image from eeg_epochs

• eeg_ICA: Plot component image from eeg_ICA
