select_elecs: Select electrodes from a given dataset

In neuroconductor-devel-releases/eegUtils: A collection of utilities for EEG analysis

Description

This is a generic function for selection of electrodes from an EEG dataset.

Usage

select_elecs(data, ...)

## Default S3 method:
select_elecs(data, electrode = NULL, keep = TRUE,
  ...)

## S3 method for class 'eeg_data'
select_elecs(data, electrode, keep = TRUE,
  df_out = FALSE, ...)

## S3 method for class 'eeg_evoked'
select_elecs(data, electrode = NULL, keep = TRUE,
  df_out = FALSE, ...)

## S3 method for class 'eeg_ICA'
select_elecs(data, component, keep = TRUE,
  df_out = FALSE, ...)

## S3 method for class 'eeg_tfr'
select_elecs(data, electrode, keep = TRUE,
  df_out = FALSE, ...)

Arguments

data	An EEG dataset.
...	Arguments used with related methods
electrode	A character vector of electrode labels for selection or removal.
keep	Defaults to TRUE. Set to false to *remove* the selected electrodes.
df_out	Defaults to FALSE. Set to TRUE to return a dataframe rather than an eeg_data object.
component	Component to select

Value

Data frame with only data from the chosen electrodes

eeg_data object with selected electrodes removed/kept.

Methods (by class)

• default: Select electrodes from a generic data frame.

• eeg_data: Select electrodes from a eeg_data object.

• eeg_evoked: Select electrode from an eeg_evoked object

• eeg_ICA: Select components from eeg_ICA objects.

• eeg_tfr: Select electrodes from eeg_tfr objects.
