R Markdown centers on executable code chunks embedded alongside narrative text. These blocks of code can be R (or other languages) and are run when you render the document, with the results—plots, tables, and other outputs—automatically woven into the final file. This makes reports reproducible, since the analysis and its results live in one place and can be regenerated simply by knitting the document. It also uses Markdown for formatting, and can be rendered to HTML, PDF, or Word with open tooling like knitr and pandoc. The other options don’t fit because R Markdown isn’t just binary data storage, it doesn’t require proprietary software, and it does support text formatting.
