plot_tfr: Time-frequency plot

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

Time-frequency plot

Description

Creates a time-frequency plot of an eeg_tfr object. The plot has time on the x-axis and frequency on the y-axis. If no electrode is supplied, it will average over all electrodes.

Usage

plot_tfr(
  data,
  electrode = NULL,
  time_lim = NULL,
  freq_range = NULL,
  baseline_type = "none",
  baseline = NULL,
  fill_lims = NULL,
  interpolate = FALSE,
  na.rm = TRUE,
  fun.data = mean
)

Arguments

data	Object of class eeg_tfr
electrode	Electrode to plot. If none is supplied, averages over all electrodes.
time_lim	Time limits of plot.
freq_range	Vector of two numbers. (e.g. c(8, 40)).
baseline_type	baseline correction to apply. Defaults to none.
baseline	Baseline period
fill_lims	Custom colour scale (i.e. range of power). e.g. c(-5, 5).
interpolate	Interpolation of raster for smoother plotting.
na.rm	Remove NA values silently (TRUE) or with a warning (FALSE). Defaults to TRUE.
fun.data	Statistical function to use for averaging over electrodes/conditions. Defaults to mean. Alternatively, supply weighted.mean, which will attempt to weight separate conditions appropriately.

Details

Various different baseline options can be applied here (e.g. "db" for decibels, "pc" for percent change, "divide" for division; see rm_baseline for details).

Value

A ggplot object
