Provides an interface to the 'PubChem' database via the PUG REST <https://pubchem.ncbi.nlm.nih.gov/docs/pug-rest> and 
            PUG View <https://pubchem.ncbi.nlm.nih.gov/docs/pug-view> services. This package allows users to automatically 
            access chemical and biological data from 'PubChem', including compounds, substances, assays, and various other data types. 
            Functions are available to retrieve data in different formats, perform searches, and access detailed annotations.

A toolbox for making R functions and capabilities more
    accessible to students and professionals from Epidemiology and
    Public Health related disciplines. Includes a function to report 
    coefficients and confidence intervals from models using robust
    standard errors (when available), functions that expand 'ggplot2'
    plots and functions relevant for introductory papers in Epidemiology 
    or Public Health. Please note that use of the 
    provided data sets is for educational purposes only.

These are harmonized datasets produced as part of the Clinical 
    Trials Network (CTN) protocol number 0094. This is a US National Institute
    of Drug Abuse (NIDA) funded project; to learn more go to
    <https://ctnlibrary.org/protocol/ctn0094/>. These are datasets which have
    the data harmonized from CTN-0027 (<https://ctnlibrary.org/protocol/ctn0027/>),
    CTN-0030 (<https://ctnlibrary.org/protocol/ctn0030/>), and CTN-0051 
    (<https://ctnlibrary.org/protocol/ctn0051/>).

Engineered features and "helper" functions ancillary to the
    'public.ctn0094data' package, extending this package for ease of use (see 
    <https://CRAN.R-project.org/package=public.ctn0094data>). This
    'public.ctn0094data' package contains harmonized datasets from some of the
    National Institute of Drug Abuse's Clinical Trials Network (NIDA's CTN)
    projects. Specifically, the CTN-0094 project is to harmonize and de-identify
    clinical trials data from the CTN-0027, CTN-0030, and CTN-51 studies for
    opioid use disorder. This current version is built from 'public.ctn0094data'
    v. 1.0.6.
