Benefits of Quarto

From the R user point of view: Decoupling from R

  • Quarto is multi-core and multi-engine
  • Dedicated CLI
  • Unlike Rmd / Jupyter notebooks, Quarto is not tied to a language1
  • Compatible with your editor (Jupyter Lab, Neovim, VS Code, RStudio, etc), with many visual edition modes available
  • Makes collaboration easier

Quarto highlights

  • Consistent implementation of attractive and handy features across outputs: tabsets, code-folding, syntax highlighting, etc.
  • More accessible defaults as well as better support for accessibility.
  • Guardrails, particularly helpful for new learners: YAML completion, informative syntax errors, etc.
  • Support for other languages like Python, Julia, Observable, and more via Jupyter engine for executable code chunks.
