Parsing R code is key to build tools such as linters and stylers.
    This package provides a binding to the 'Rust' crate 'ast-grep' so that one
    can parse and explore R code.

Data sets and examples from National Health and Nutritional Examination Survey (NHANES).

Routines for astrochronologic testing, astronomical time scale construction, and time series analysis <doi:10.1016/j.earscirev.2018.11.015>. Also included are a range of statistical analysis and modeling routines that are relevant to time scale development and paleoclimate analysis.

Miscellaneous astronomy functions, utilities, and data.

A comprehensive toolkit for astronomical and cosmological
    computations. Provides functions for angular coordinate conversions
    (degrees, hours-minutes-seconds, degrees-minutes-seconds, and radians),
    access to fundamental physical constants, queries to the Gaia Archive TAP
    (Table Access Protocol) service, cosmological distance calculations,
    early-universe thermal physics including photon density, 'Saha' equation
    solutions, and a full thermal-cosmology module covering the Hubble rate in
    the radiation-dominated era, effective relativistic degrees of freedom,
    entropy density, equilibrium yields, the Boltzmann relic-abundance
    ('pebble') equation for WIMP freeze-out, the freeze-out temperature solver,
    and the Peebles equation for hydrogen recombination. Also includes the
    Drake equation for estimating the number of communicating extraterrestrial
    civilisations in the Milky Way.

Provides access to the 'Astronomy Engine' C library
    (<https://github.com/cosinekitty/astronomy>) by Don Cross. The library
    calculates positions of the Sun, Moon, and planets, and predicts
    astronomical events such as rise/set times, lunar phases, equinoxes,
    solstices, eclipses, and transits. It is based on the 'VSOP87' planetary
    model and is accurate to within approximately one arcminute. This package
    bundles the single-file C source so that other R packages can link against
    it via 'LinkingTo' without shipping their own copy.
