R package to query and get data out of a Pumilio sound archive system (http://ljvillanueva.github.io/pumilio/).

Estimates power, minimum detectable effect size (MDES) and sample size requirements. The context is multilevel randomized experiments with multiple outcomes. The estimation takes into account the use of multiple testing procedures. Development of this package was supported by a grant from the Institute of Education Sciences (R305D170030).

High-performance Unicode and Punycode processing for
    internationalized domain names. The 'puny_encode()' / 'puny_decode()'
    helpers are a low-level, RFC 3492 compliant Punycode codec for domain
    labels (the 'xn--' ASCII-Compatible Encoding of RFC 5890/5891); they
    perform the raw transform plus letter-digit-hyphen checks and do not
    apply Unicode IDNA normalization. 'host_normalize()' is the Unicode
    Technical Standard #46 host-normalization entry point, mapping a host
    name to a canonical lowercase ASCII comparison form (non-transitional
    profile, pinned Unicode version). The 'url_encode()' / 'url_decode()' /
    'parse_url()' helpers do best-effort host extraction and rewriting in
    URL-shaped strings and are deliberately not RFC 3986 / WHATWG URL
    parsers or canonicalizers; they are deprecated in favor of dedicated
    URL packages. Aimed at host normalization and data analysis workflows.
    Used as the Punycode and IDNA engine by the 'pslr' and 'rurl' packages.

Contains model fitting functions for linear and non-linear adsorption kinetic and diffusion models. Adsorption kinetics is used for characterizing the rate of solute adsorption and the time necessary for the adsorption process. Adsorption kinetics offers vital information on adsorption rate, adsorbent performance in response time, and mass transfer processes. In addition, diffusion models are included in the package as solute diffusion affects the adsorption kinetic experiments. This package consists of 20 adsorption and diffusion models, including Pseudo First Order (PFO), Pseudo Second Order (PSO), Elovich, and Weber-Morris model (commonly called the intraparticle model) stated by Plazinski et al. (2009) <doi:10.1016/j.cis.2009.07.009>. This package also contains a summary function where the statistical errors of each model are ranked for a more straightforward determination of the best fit model.
