Uses non-linear regression to statistically compare two circadian rhythms.
    Groups are only compared if both are rhythmic (amplitude is non-zero).
    Performs analyses regarding mesor, phase, and amplitude, reporting on estimates and statistical differences, for each, between groups.
    Details can be found in Parsons et al (2020) <doi:10.1093/bioinformatics/btz730>.

A generic sleep–wake cycle detection algorithm for analyzing unlabeled actigraphy data. 
    The algorithm has been validated against event markers using data from the Multi-Ethnic Study of Atherosclerosis (MESA) Sleep study, 
    and its methodological details are described in Chen and Sun (2024) <doi:10.1098/rsos.231468>. 
    The package provides functions to estimate sleep metrics (e.g., sleep and wake onset times) and circadian rhythm metrics 
    (e.g., mesor, phasor, interdaily stability, intradaily variability), as well as tools for screening actigraphy quality, 
    fitting cosinor models, and performing parametric change point detection. 
    The workflow can also be used to segment long actigraphy sequences into regularized structures for physical activity research.

Wraps the 'CIRCE' (<https://github.com/ohdsi/circe-be>) 'Java'
  library allowing cohort definition expressions to be edited and converted to 
  'Markdown' or 'SQL'.

Light-weight functions for computing descriptive statistics in different circular spaces (e.g., 2pi, 180, or 360 degrees), to handle angle-dependent biases, pad circular data, and more. Specifically aimed for psychologists and neuroscientists analyzing circular data. Basic methods are based on Jammalamadaka and SenGupta (2001) <doi:10.1142/4031>, removal of cardinal biases is based on the approach introduced in van Bergen, Ma, Pratte, & Jehee (2015) <doi:10.1038/nn.4150> and Chetverikov and Jehee (2023) <doi:10.1038/s41467-023-43251-w>.

Tools for interacting with the 'Circle CI' API
    (<https://circleci.com/docs/api/v2/>). Besides executing common tasks
    such as querying build logs and restarting builds, this package also
    helps setting up permissions to deploy from builds.
