Introduction to defineR

The defineR package is an open-source R language package to create define.xml documents that are suitable for submission to the U.S. Food and Drug Administration. The package has the following capabilities:

1. Create the define.xml document
2. Perform consistency checks and schema validation of the define.xml
3. Write and view a report of the consistency checks
4. Produce the define.html transformation of define.xml
5. Generate the metadata templates needed to create the define.xml

Currently, the package only supports version 2.0.0 of the define.xml for SDTM and ADaM. Future enhancements to the package will add support for define version 2.1.
