erp_raster: ERP raster plot

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

Description

Create a plot showing the ERP at every channel as a single ERP image. By default, this attempts to find channel locations and rearrange the channels such that spatial patterns on the scalp are more discernible. It orders the rows from the most posterior electrode on the right hemisphere to the most anterior electrode on the left hemisphere, with midline electrodes in the middle. If no locations are found, it simply displays the data in its original order.

Usage

erp_raster(data, anat_order = TRUE, time_lim = NULL, clim = NULL,
  interpolate = FALSE)

Arguments

data	An eeg_epochs object
anat_order	Arrange the channels in a more anatomically representative order.
time_lim	Time limits of plot - should be a character vector (e.g. c(-.2, .5))
clim	Character vector of min and max values of plotting colour range. e.g. c(-5,5). Defaults to min and max.
interpolate	Smooth the raster plot. Defaults to FALSE.
