plot_butterfly: Create a butterfly plot from timecourse data

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

Description

Typically event-related potentials/fields, but could also be timecourses from frequency analyses for single frequencies. Output is a ggplot2 object. CIs not possible.

Usage

plot_butterfly(data, ...)

## Default S3 method:
plot_butterfly(data, time_lim = NULL, group = NULL,
  facet = NULL, baseline = NULL, colourmap = NULL, legend = TRUE,
  continuous = FALSE, browse_mode = FALSE, ...)

## S3 method for class 'eeg_evoked'
plot_butterfly(data, time_lim = NULL,
  group = NULL, facet = NULL, baseline = NULL, colourmap = NULL,
  legend = TRUE, continuous = FALSE, browse_mode = FALSE, ...)

## S3 method for class 'eeg_stats'
plot_butterfly(data, time_lim = NULL, group = NULL,
  facet = NULL, baseline = NULL, colourmap = NULL, legend = TRUE,
  continuous = FALSE, browse_mode = FALSE, ...)

## S3 method for class 'eeg_data'
plot_butterfly(data, time_lim = NULL,
  baseline = NULL, legend = TRUE, browse_mode = FALSE, ...)

## S3 method for class 'eeg_epochs'
plot_butterfly(data, time_lim = NULL,
  baseline = NULL, legend = TRUE, browse_mode = FALSE, ...)

Arguments

data	EEG dataset. Should have multiple timepoints.
...	Other parameters passed to plot_butterfly
time_lim	Character vector. Numbers in whatever time unit is used specifying beginning and end of time-range to plot. e.g. c(-.1,.3)
group	Group lines by a specificed grouping variable.
facet	Create multiple plots for a specified grouping variable.
baseline	Character vector. Times to use as a baseline. Takes the mean over the specified period and subtracts. e.g. c(-.1, 0)
colourmap	Attempt to plot using a different colourmap (from RColorBrewer). (Not yet implemented)
legend	Plot legend or not.
continuous	Is the data continuous or not (I.e. epoched)
browse_mode	Custom theme for use with browse_data.

Value

ggplot2 object showing ERPs for all electrodes overlaid on a single plot.
