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.

Focused
We think Focused is the new benchmark for markdown writing apps that will enable you to really focus on your work. Building on the amazing Typed app from Realmac Software, Codebots is proud to bring you Focused for Mac. Focused is not just a distraction-free writing app, it’s the first writing app that actually aids your focus. Markdown was created by John Gruber as an easy to read plain text format that allows you to create web based content with no HTML knowledge. The syntax that is used when writing markdown allows you to define the intent of different elements in the markdown document e.g. a # in front of a word indicates that the word is to be formatted and displayed as a Title. Markdown removes the need to memorize complex HTML tags, and an ever growing number of blogging platforms allow markdown to be used for content creation. No clutter, no distractions. Just a perfectly crafted set of tools to help you write and stay focused on the task at hand.

The lack of support for rich text is due to technical limitations and limited development resources. We are evaluating the cost/benefit of investing in rich text support of iOS. Meanwhile, we strongly recommend opting for plain text and markdown format for your documents. Macworld has a great article explaining why opting for plain text today is a good idea.
