A new gitbook - learnR

Gitbook is rather a relatively new concept on the web. It provides a user-friendly framework for authors to write and produce online books with beautiful illustrations and responsive interactions. It allows authors to write in Markdown syntax, which is very easy to learn and use, so that they can focus more on the contents they try to produce than the layout and styles of the contents.

There are already couple of books online. However, I can't find any authors writing a gitbook related to R. A month ago, I needed to give lectures to introduce R to my team, so I prepared a variety of code that covers a wide range of topics from the absolute basics to advanced programming concepts and practices.

I created learnR project and decided to produce a gitbook based on that code. Therefore I transformed the repo to a new gitbook repo entitled learnR for R users to better understand the basics and underlying mechanisms of R so as to solve problems using R with easier and more elegant code and techniques.

Thanks to Jason Bryer's Rgitbook package! It allows me to write the book in R Markdown and transform the output to markdown.

The gitbook is still in its early stage, but it's already online for preview, and the contents are planned as the following:
