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.
