Select frequencies

Source: R/data_selection.R
select_freqs.Rd

Select specific frequencies from eeg_tfr objects. Can be used to selecting either single frequencies or anything within a range.

Usage

select_freqs(data, freq_range)

# S3 method for class 'eeg_tfr'
select_freqs(data, freq_range)

Arguments

data

An eeg_tfr object.

freq_range

The range of frequencies to retain. Can be a scale or the lower and upper bounds. (e.g. c(5, 30))

Methods (by class)

  • select_freqs(eeg_tfr): Function for selecting specific frequencies from eeg_tfr objects.

Examples

demo_tfr <- compute_tfr(demo_epochs, foi = c(4, 30), n_freq = 10, n_cycles = 5)
#> Computing TFR using Morlet wavelet convolution
#> Output frequencies using linear spacing: 4 6.89 9.78 12.67 15.56 18.44 21.33 24.22 27.11 30
#> Removing channel means per epoch...
#> Returning signal averaged over all trials.
