  • One of the most popular languages used by statisticians and data sicentists
git pull

R Markdown and Notebook

R Markdown

  • R Markdown provides an authoring framework for data science.
     

  • You can use a single R Markdown file to both

    save and execute code, and generate high quality reports that can be shared with an audience.

R Notebook

  • An R Notebook is an R Markdown document with chunks that can be executed independently and interactively, with output visible immediately beneath the input.

Create a Notebook
