Plot Global Field Power of EEG Signals

Description

Global Field Power (Lehmann & Skrandies, 1980) is a way to quantify the amount of activity in the overall electroencephalographic signal at a given timepoint. It corresponds to the spatial standard deviation.

Usage

plot_gfp(data, cols = NULL, keep_trials = FALSE)

Arguments

`data`	An `eeg_epochs` object
`cols`	Condition columns from the `epochs` metadata to calculate GFP separately for different conditions.
`keep_trials`	Calculate GFP for each epoch separately, then average over epochs.

Examples

plot_gfp(demo_spatial)
plot_gfp(demo_spatial, keep_trials = TRUE)
plot_gfp(demo_spatial, cols = "epoch_labels")
plot_gfp(demo_spatial, cols = "epoch_labels", keep_trials = TRUE)
