Browse EEG data

Source: R/data_viewers.R
browse_data.Rd

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.

Usage

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, ...)

Arguments

data

eeg_data, eeg_epochs, or eeg_ICA object to be plotted.

...

Other parameters passed to browsing functions.

sig_length

Length of signal to be plotted initially (seconds if continuous, epochs if epoched).

downsample

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

Value

A character vector of component names selected for rejection.

Methods (by class)

  • browse_data(eeg_ICA): View eeg_ICA component properties

  • browse_data(eeg_data): Browse continuous EEG data.

  • browse_data(eeg_epochs): Browse epoched EEG data.
