Downsampling EEG data

Description

Performs low-pass anti-aliasing filtering and downsamples EEG data by a specified factor. This is a wrapper for decimate from the signal package. Note that this will also adjust the event table, moving events to the nearest time remaining after downsampling

Usage

eeg_downsample(data, ...)

## S3 method for class 'eeg_data'
eeg_downsample(data, q, ...)

## S3 method for class 'eeg_epochs'
eeg_downsample(data, q, ...)

Arguments

data	An eeg_data object to be downsampled
...	Parameters passed to functions
q	Integer factor to downsample by

Methods (by class)

• eeg_downsample(eeg_data): Downsample eeg_data objects

• eeg_downsample(eeg_epochs): Downsample eeg_epochs objects
