Select epochs

This is a generic function for selecting epochs from an epoched data set.

Usage

select_epochs(data, ...)

# Default S3 method
select_epochs(data, ...)

# S3 method for class 'eeg_epochs'
select_epochs(
  data,
  epoch_events = NULL,
  epoch_no = NULL,
  keep = TRUE,
  df_out = FALSE,
  ...
)

# S3 method for class 'eeg_ICA'
select_epochs(
  data,
  epoch_events = NULL,
  epoch_no = NULL,
  keep = TRUE,
  df_out = FALSE,
  ...
)

# S3 method for class 'eeg_tfr'
select_epochs(
  data,
  epoch_events = NULL,
  epoch_no = NULL,
  keep = TRUE,
  df_out = FALSE,
  ...
)

Arguments

data

eeg_epochs object from which to select epochs.

...

Parameters passed to specific methods

epoch_events

Select epochs containing any of the specified events. Can be numeric or a character string. Will override any epoch_no input.

epoch_no

Select epochs by epoch number.

keep

Defaults to TRUE, meaning select the specified epochs. Set to FALSE to remove specified epochs.

df_out

Output a data.frame instead of an eeg_data object.

Methods (by class)

• select_epochs(default): Select from generic object

• select_epochs(eeg_epochs): Selection of epochs from eeg_epochs objects.

• select_epochs(eeg_ICA): Selection of epochs from eeg_ICA objects.

• select_epochs(eeg_tfr): Selection of epochs from eeg_tfr objects.
