# eeguana 0.1.7.9000

• New features:
  • The argument .ref of eeg_rereference() now allows "tidyselect".
  • write_vhdr() writes BrainVision 2.0 files (experimental).
  • eeg_psd() computes the power spectral density (PSD) of a en EEG signal (using only the Welch method for now).
  • eeg_band_power() computes power bands.
  • na_omit() removes NA values from eeg_lst objects.
  • as_tidytable() added.
  • sampling_rate() shows the sampling rate of an object.
  • eeg_unsegment() was added.
• Modifying channels with channels_tbl() is much faster now.
• Signal filtering is slightly faster and uses the gsignal package.
• BUGS:
  • some brainvision files produced by eeglab couldn't be read now work
• DEPRECATIONS:
  • The argument .all_chs of eeg_events_to_NA was deprecated in favor of the more flexible .n_chs.

• Changes:
  • The introductory vignette (https://bnicenboim.github.io/eeguana/articles/intro.html) was slightly modified.
  • eeg_segment() accepts unpaired events when end argument is used, and should be able to deal with duplicated triggers.
  • eeg_artif_peak() detect peaks in the EEG signal.
  • eeg_ica_cor_tbl() and eeg_ica_var_tbl show the correlation of components (ICA) with EOG channels and their variance explained.
  • eeg_ica_summary_tbl() summarizes eeg_ica_cor_tbl() and eeg_ica_var_tbl().

eeguana 0.1.0.9000. First fully functional version

eeguana 0.1.0.9000

• Changes
  • New vignette that introduces the package here.
  • FastICA was implemented in eeg_ica().

    • summarize_all_ch(...) should be changed to summarize_at(channel_names(.),...).
    • summarize_at_ch(...) should be changed to summarize_at(...).
    • ch_filt_*() functions were renamed to eeg_filt_*() and they get a ... argument to select the relevant channels.
    • ch_baseline() was renamed to eeg_baseline().
• Bugs
  • Events in Brain Vision version 1.0 file are now correctly read.
  • Various minor bugs fixed.

First official development version of eeguana

eeguana: A package for flexible manipulation of EEG data. eeguana provides a
data.table powered framework for manipulating EEG data with
dplyr-based functions (e.g., mutate, filter, summarize) extended
to a new class eeg_lst, other EEG-specialized functions, and ggplot
wrapper functions. The new class is inspired by tidyverse principles but
it’s not really “tidy” (due to space considerations), it’s a list of (i)
a wide data table (signal_tbl) that contains the signal amplitudes
at every sample point of the EEG, (ii) an events data table with
information about markers (or triggers), blinks and other exported
information, and (iii) a long table with experimental information, such
as participant number (recording), conditions, etc.

There is still no released version of eeguana. The package is in
the early stages of development, and it will be subject to a lot of
changes. To install the latest version from github use:

devtools::install_github("bnicenboim/eeguana")
