Channel interpolation

Source: R/current_source_density.R

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

interp_elecs(data, bad_elecs, ...)

# S3 method for eeg_data

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)
