Tools for getting historical weather information and forecasts 
    from wunderground.com. Historical weather and forecast data includes, but 
    is not limited to, temperature, humidity, windchill, wind speed, dew point, 
    heat index. Additionally, the weather underground weather API also includes 
    information on sunrise/sunset, tidal conditions, satellite/webcam imagery, 
    weather alerts, hurricane alerts and historical high/low temperatures.

Methods to compute chemical similarity between two or more reactions and molecules. Allows masking of chemical substructures for weighted similarity computations. Uses packages 'rCDK' and 'fingerprint' for cheminformatics functionality. Methods for reaction similarity and sub-structure masking are as described in: Giri et al. (2015) <doi:10.1093/bioinformatics/btv416>.

Facilities for running simulations from ordinary
    differential equation ('ODE') models, such as pharmacometrics and other
    compartmental models.  A compilation manager translates the ODE model
    into C, compiles it, and dynamically loads the object code into R for
    improved computational efficiency.  An event table object facilitates
    the specification of complex dosing regimens (optional) and sampling
    schedules.  NB: The use of this package requires both C and
    Fortran compilers, for details on their use with R please see
    Section 6.3, Appendix A, and Appendix D in the "R Administration and
    Installation" manual. Also the code is mostly released under GPL.  The
    'VODE' and 'LSODA' are in the public domain.  The vendored 'SUNDIALS'
    'CVODE' sources and headers are released under the BSD-3-Clause license.
    The information is available in the inst/COPYRIGHTS.

Provides the log-likelihoods with gradients from 'stan'
    (Carpenter et al (2015), <doi:10.48550/arXiv.1509.07164>) needed
    for generalized log-likelihood estimation in 'nlmixr2'
    (Fidler et al (2019) <doi:10.1002/psp4.12445>). This is
    split of to reduce computational burden of recompiling 'rxode2'
    (Wang, Hallow and James (2016) <doi:10.1002/psp4.12052>) which runs
    the 'nlmixr2' models during estimation.
