R markdown allows connecting data, code, and text into reports, presentations, and other documents. It works with R, Python, and Bash code. The rmdformats package creates clean HTML documents from R markdown files using different template designs like "readthedown" and "docute". Templates allow formatting code and content into pages, tables of contents, and other features. Parameters control template features such as figure sizes and code folding. Resources for learning more about R markdown and rmdformats were also provided.
