R Markdown enables easy authoring of reproducible web reports from R. It offers:

• Easy creation of web reports from R that can be automatically regenerated whenever underlying code or data changes.
• A highly accessible syntax (markdown) which lower the barriers to entry for reproducible research.
• Output of a standalone HTML file (with images embedded directly in the file) that is easy to share using email, Dropbox, or by deploying to a web server.
• Support for publishing dynamic and interactive web content.

This article includes an overview of how to use R Markdown within RStudio. For more specific details on syntax and implementation, see the R Markdown article.
