plot_tfr: Time-frequency plot

In neuroconductor/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.

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
