Channel interpolation

Source: R/current_source_density.R
interp_elecs.Rd

Interpolate EEG channels using a spherical spline (Perrin et al., 1989; 1990). The data must have channel locations attached.

Usage

interp_elecs(data, bad_elecs, ...)

# S3 method for class 'eeg_data'
interp_elecs(data, bad_elecs, ...)

Arguments

data

Data as a eeg_data or eeg_epochs object.

bad_elecs

Name(s) of electrode(s) to interpolate.

...

Other parameters passed to the functions.

Methods (by class)

  • interp_elecs(eeg_data): Interpolate EEG channel(s)
