‘bookdown’ is a software package for writing books or documents based on R language (R Core Team 2016) and Markdown syntax. It is something like Microsoft Word, but more elegant, more powerful, and easier. If you know LaTeX, it would be much helpful to get into ‘bookdown’. If not, don’t worry, it is the reason why I wrote this book. With ‘bookdown’, users can
easily insert table of contents, figures and tables with cross-reference, footnotes, and index;
easily embed equations, citations, R scripts;
obtain multiple formats of outputs such as pdf, word and html files;
have the best experience of writing reproducible documents.
