eeguana 0.1.11.9001

Bug fixed

• could not find function "across." error fixed (thanks @prattems)

eeguana 0.1.10.9001

New Features

• Added chs_mean method for psd_list objects.
• Introduced experimental read_fif() function to read fif files created by MNE Python.
• New install_py_eeguana() function to install the necessary Python packages for reading fif files.

Bugs and Improvements

• Improved behavior of channel_dbl and sample_int classes.
• Enhanced annotate_events() function to allow plotting even if there are no events.

eeguana 0.1.9.9001

• fix installation of the dependency tidytable.
• added annotate_electrodes() to add electrode labels to a topographic plot. (Previously this was done with geom_text()).

eeguana 0.1.8.9001

• fix of minor bug affecting eeg_artif_step(), when the number of samples in window was odd.

eeguana 0.1.8.9000

• as_eeg_lst() makes eeg_lst objects created with previous versions of eeguana compatible with the current version.

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.

eeguana 0.1.6.9000

• Breaking change: _at, _if, _all functions don't work anymore. Now one should use the new across() (or across_ch()) notation. If your code doesn't work anymore and you don't know how to fix it, please post it in https://github.com/bnicenboim/eeguana/discussions
• Potential breaking change: when segments with repeated columns are joined, they use data.table notation (i...) rather than dplyr notation. This might affect the join family and eeg_segment.
• dplyr-like functions get an eeg_ prefix (e.g., eeg_mutate, eeg_filter), they still work without the prefix (for now).
• NEW FEATURES:
  • filters have more options (including IIR, experimental).
  • read eeglab set files (still experimental)
• documentation:
  • more examples
• internal changes:
  • removed dependency with stringr
  • changed internal structure of eeg_lst, the segments table is a data.table rather than a tibble and they depend on tidytable

• Bugs:
  • weird dplyr filter behavior fixed #136
• Changes
  • plot_components() behaves more similarly to plot_topo()

  • Much faster mutate functions
  • Better error messages for reading Brain Vision files @jaromilfrossard
