iso8601_year

<code>iso8601_year()</code> converts a character vector whose values represent years to
four-digit years.

internal

An Electronic Data Capture system (EDC) and Data Standard agnostic
solution that enables the pharmaceutical programming community to develop
Clinical Data Interchange Standards Consortium (CDISC)
Study Data Tabulation Model (SDTM) datasets in R. The reusable algorithms
concept in 'sdtm.oak' provides a framework for modular programming and can
potentially automate the conversion of raw clinical data to SDTM through
standardized SDTM specifications. SDTM is one of the required standards for data
submission to the Food and Drug Administration (FDA) in the United States and
Pharmaceuticals and Medical Devices Agency (PMDA) in Japan. SDTM standards
are implemented following the SDTM Implementation Guide as defined by
CDISC <https://www.cdisc.org/standards/foundational/sdtmig>.
