The R Markdown

The rmarkdown package helps you create dynamic analysis documents that combine code, rendered output (such as figures), and prose. You bring your data, code, and ideas, and R Markdown renders your content into a polished document that can be used to:

  • Do data science interactively within the RStudio IDE,
  • Reproduce your analyses,
  • Collaborate and share code with others, and
  • Communicate your results with others. R Markdown documents can be rendered to many output formats including HTML documents, PDFs, Word files, slideshows, and more, allowing you to focus on the content while R Markdown takes care of your presentation.

The R Markdown ecosystem

You can run Python or Julia code in an R Markdown document, but… you have to install R.

Conclusion

  • Versatile, multi-languages, quarto is a great tool for publishing.
  • Quarto CLI is really a game changer.
  • Very well documented.
  • Publishing and hosting is really easy.
  • Very powerful syntax but the level of knowledge needed is still quite high.
  • Well integrated with RStudio and VSCode but can be used on the command line with a text editor which was difficult to do with the RMarkdown tools.
