dfc | Computes the Degree of Function coupling (DFC), Harmonic Part (HP) and Weekly Lomb-Scargle Spectrum (LSP Spec) for one variable in an activity dataset. The dataset should be digiRhythm friendly.
df_act_info | Outputs some information about the activity dataframe
dgm_periodicity | Returns the periodicity of a digiRhythm dataframe
diurnality | Computes the diurnality index based on an activity dataframe
import_raw_activity_data | Reads Raw Activity Data from csv files
is_dgm_friendly | Informs if a dataset is digiRhythm Friendly
levopt | Returns the level given the p-value computed with pbaluev (2008). Copied from the LOMB library.
lomb_scargle_periodogram | Computes the Lomb Scargle Periodogram and returns the information needed for computing the DFC and HP. A plot visualizing the Harmonic Frequencies presence in the spectrum is possible. The function is inspired from the Lomb library in a great part, with modifications to fit the requirements of harmonic powers and computation of the DFC. This function is inspired by the lsp function from the lomb package and adapted to add different colors for harmonic and non harmonic frequencies in the signal. For more information about lomb::lsp, please refer to: https://cran.r-project.org/web/packages/lomb/
pbaluev | Returns p-value of a frequency peack according to pbaluev (2008) given Z, fmax and tm. Copied from the LOMB library.
print_v | Print if Verbose is true
remove_activity_outliers | Remove outliers from the data
resample_dgm | Change the sampling of a digiRhythm friendly dataset
sliding_DI | Computes the diurnality index, using different start and end definitions for each day and night, based on an activity dataframe
timedata | timedata Dataset of start and end of day and night
