plot_timecourse: Plot 1-D timecourse data.

In neuroconductor/eegUtils: Utilities for Electroencephalographic (EEG) Analysis

Plot 1-D timecourse data.

Description

Typically event-related potentials/fields, but could also be timecourses from frequency analyses for single frequencies. Averages over all submitted electrodes. Output is a ggplot2 object.

Usage

plot_timecourse(data, ...)

## S3 method for class 'data.frame'
plot_timecourse(
  data,
  electrode = NULL,
  time_lim = NULL,
  add_CI = FALSE,
  baseline = NULL,
  colour = NULL,
  color = NULL,
  mapping = NULL,
  ...
)

## S3 method for class 'eeg_evoked'
plot_timecourse(
  data,
  electrode = NULL,
  time_lim = NULL,
  add_CI = FALSE,
  baseline = NULL,
  colour = NULL,
  color = NULL,
  mapping = NULL,
  ...
)

## S3 method for class 'eeg_ICA'
plot_timecourse(
  data,
  component = NULL,
  time_lim = NULL,
  add_CI = FALSE,
  baseline = NULL,
  colour = NULL,
  color = NULL,
  mapping = NULL,
  ...
)

## S3 method for class 'eeg_epochs'
plot_timecourse(
  data,
  electrode = NULL,
  time_lim = NULL,
  add_CI = FALSE,
  baseline = NULL,
  colour = NULL,
  color = NULL,
  mapping = NULL,
  ...
)

## S3 method for class 'eeg_group'
plot_timecourse(
  data,
  electrode = NULL,
  time_lim = NULL,
  add_CI = FALSE,
  baseline = NULL,
  colour = NULL,
  color = NULL,
  mapping = NULL,
  ...
)

## S3 method for class 'eeg_tfr'
plot_timecourse(
  data,
  electrode = NULL,
  time_lim = NULL,
  add_CI = FALSE,
  baseline = NULL,
  colour = NULL,
  color = NULL,
  mapping = NULL,
  freq_range = NULL,
  type = "divide",
  ...
)

Arguments

data	EEG dataset. Should have multiple timepoints.
...	Other arguments passed to methods.
electrode	Electrode(s) to plot.
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)
add_CI	Add confidence intervals to the graph. Defaults to 95 percent between-subject CIs.
baseline	Character vector. Times to use as a baseline. Takes the mean over the specified period and subtracts. e.g. c(-.1,0)
colour	Variable to colour lines by. If no variable is passed, only one line is drawn.
color	Alias for colour.
mapping	A ggplot2 aes() mapping.
component	name or number of ICA component to plot
freq_range	Choose a specific frequency range to plot
type	Type of baseline correction to use for eeg_tfr objects

Value

Returns a ggplot2 plot object
