ar_thresh: Simple absolute value thresholding

In craddm/eegUtils: Utilities for Electroencephalographic (EEG) Analysis

Simple absolute value thresholding

Description

Reject data based on a simple absolute amplitude threshold. This marks any timepoint from any electrode.

Usage

ar_thresh(data, threshold, reject = FALSE)

## S3 method for class 'eeg_data'
ar_thresh(data, threshold, reject = FALSE)

## S3 method for class 'eeg_epochs'
ar_thresh(data, threshold, reject = FALSE)

Arguments

data	An object of class eeg_data or eeg_epochs.
threshold	In microvolts. If one value is supplied, it will be treated as a +- value.
reject	If TRUE, remove marked data immediately, otherwise mark for inspection/rejection. Defaults to FALSE.

Value

An object of class eeg_data or eeg_epochs

Methods (by class)

• ar_thresh(eeg_data): Reject data using a simple threshold.

• ar_thresh(eeg_epochs): Reject data using a simple threshold.
