A Shiny gadget for browsing EEG data and ICA decompositions interactively.
With EEG data (epoched or continuous), data can be viewed as a butterfly plot
(all electrodes overlaid) or as individual traces (electrodes "stacked"). For
eeg_ICA objects, you will instead be shown a composite of multiple
properties of the decomposition - a topography, an ERP image, an ERP, and a
power spectral density plot from 4-50 Hz.
browse_data(data, ...)
# S3 method for class 'eeg_ICA'
browse_data(data, ...)
# S3 method for class 'eeg_data'
browse_data(data, sig_length = 5, downsample = TRUE, ...)
# S3 method for class 'eeg_epochs'
browse_data(data, sig_length = 5, downsample = FALSE, ...)eeg_data, eeg_epochs, or eeg_ICA object to be plotted.
Other parameters passed to browsing functions.
Length of signal to be plotted initially (seconds if continuous, epochs if epoched).
Only works on eeg_data or eeg_epochs objects.
Reduces size of data by only plotting every 4th point, speeding up plotting
considerably. Defaults to TRUE for eeg_data, FALSE for eeg_epochs
A character vector of component names selected for rejection.
