Section B.12 💡 Reproducibility Tip:
A reproducible R Markdown document should knit successfully from top to bottom in a clean R session without manual fixes.
Because knitting re-runs every chunk in order, it helps expose missing packages, undefined objects, and hidden dependencies that can make analyses difficult to reproduce. To support this, always load required packages within the document and avoid relying on objects created outside the file.
You can check whether these criteria are met by shutting down your R session completely, opening your R Markdown file in a brand new R session, and pressing Knit.
An analysis is only reproducible if it can be re-run and understood as a complete, self-contained document.
