3  Reproducible verification in R

3.1 Learning objective

Make every verification step traceable.

3.2 Content to develop

• Record input provenance and data dictionaries.
• Record software versions, commands, and random seeds where relevant.
• Compare independently obtained results with the supplied output.
• Record discrepancies without silently modifying original evidence.

3.3 Practice task

Plan the checks needed to reproduce a supplied result. Case-specific executable checks will be added during development.

3.4 Checkpoint

Can another reader trace each conclusion to evidence and understand what remains uncertain?

3.5 Deliverable

A verification plan and environment record.
