Estimates generalized additive latent and
    mixed models using maximum marginal likelihood, 
    as defined in Sorensen et al. (2023) 
    <doi:10.1007/s11336-023-09910-z>, which is an extension of Rabe-Hesketh and
    Skrondal (2004)'s unifying framework for multilevel latent variable 
    modeling <doi:10.1007/BF02295939>. Efficient computation is done using sparse 
    matrix methods, Laplace approximation, and automatic differentiation. The 
    framework includes generalized multilevel models with heteroscedastic 
    residuals, mixed response types, factor loadings, smoothing splines, 
    crossed random effects, and combinations thereof. Syntax for model 
    formulation is close to 'lme4' (Bates et al. (2015) 
    <doi:10.18637/jss.v067.i01>) and 'PLmixed' (Rockwood and Jeon (2019) 
    <doi:10.1080/00273171.2018.1516541>).

The Darwin Core data standard is widely used to share 
  biodiversity information, most notably by the Global Biodiversity Information 
  Facility and its partner nodes; but converting data to this standard can be 
  tricky. 'galaxias' is functionally similar to 'devtools', but with a focus on 
  building Darwin Core Archives rather than R packages, enabling data to be 
  shared and re-used with relative ease. For details see 
  Wieczorek and colleagues (2012) <doi:10.1371/journal.pone.0029715>.

Calculate, plot and animate the configuration of Jupiter's four
    largest satellites (known as Galilean satellites) for a given date and time
    (UTC - Coordinated Universal Time).
    The galsat() function returns numerical values of the satellites’ positions.
    x – the apparent rectangular coordinate of the satellite with respect to the
    center of Jupiter’s disk in the equatorial plane in the units of Jupiter’s
    equatorial radius; X is positive toward the west,
    y – the apparent rectangular coordinate of the satellite with respect to the
    center of Jupiter’s disk from the equatorial plane in the units of Jupiter’s
    equatorial radius; Y is positive toward the north.
    For more details see Meeus (1988, ISBN 0-943396-22-0) "Astronomical Formulae
    for Calculators".
    The galsat_animate() function creates an animation of the Galilean
    satellites' positions. You provide the starting time, duration, the time
    step between frames, and the pause between frames.
    The function delta_t() returns the value of delta-T in units of seconds.
