Rmd files · An R Markdown (.Rmd) file is a record of your research. It contains the code that a scientist needs to reproduce your work along with the narration that a reader needs to understand your work. Reproducible Research · Atthe click of a button, or the typeof a command, you can rerun the code in an R Markdown file to reproduce your work and export the results as a finished report.  \nDynamic Documents · You can choose to export the finished report in a variety of formats, including html, pdf, MSWord, or RTF documents; html or pdf based slides, Notebooks, and more.  \nWorkflow  \n1 Open a new .Rmd file at File ▶ New File ▶ R Markdown.
