R Markdown
R Markdown documents are fully reproducible. Use a productive notebook interface to weave together narrative text and code to produce elegantly formatted output. Use multiple languages including R, Python, and SQL. R Markdown supports dozens of static and dynamic output formats including HTML, PDF, MS Word, Beamer, HTML5 slides, Tufte-style handouts, books, dashboards, shiny applications, scientific articles, websites, and more. R Markdown provides an authoring framework for data science. You can use a single R Markdown file to both. When you open the file in the RStudio IDE, it becomes a notebook interface for R. You can run each code chunk by clicking the icon. RStudio executes the code and display the results inline with your file.
