![]() Knitr is very powerful, but for now I just give the basics. Fortunately, R studio and RMarkdown provide a great and relatively straightforward way to engage in literate programming with the use of the package knitr (see as well this website). However, for educational and smaller scientific purposes, such as theses, papers and tutorials, it can be a great tool. Some people argue to keep code and text (documentation) separated. Whether literate programming is always a good idea for a larger project is debatable. With one command both text (say your paper) and the analysis are generated. Literate programming basically means that code and text (documentation) are written together, which is wonderful for, e.g., reproducible research. Literate programming is a concept initially coined by the very distinguished computer scientist Donald Knuth (the same guy who wrote one the most (in)famous mark-up languages of them all-LaTeX). So, clicking on File > New File > R Markdown already gives an example file that enables you to create a webpage or Word document.

They bundled this in a package called RMarkdown, although it actually still is Markdown with some additional flavour. Heres a simple little trick that I dont see many people using. Ordered list items start with numbers, which can also be nested. Other types of applications are blogging with Wordpress and the online (nerd) repository GitHub (btw, all resources for this book can be found on Github of course in markdown).īuilding on Markdown, the people of RStudio added some additional features, most notably including the possibility of adding equations and literature programming (writing text/documentation and code together). R Markdown is an authoring framework for data science that enables easy creation of. It works more or less similar to the well known writing application Scrivener (which can actually import and export Markdown). Therefore, markdown became very popular for writers who wanted to write distraction free. One of the most attractive features of markdown is that it can be converted or exported to other formats, most notably pdf (via LaTeX) and html. Originally, John Gruber created the language in 2004 and is extremely simple (hence the name mark down): there is just not that many syntax to learn. Here, we deal with R Markdown which is a variant on the now very popular Markdown language. For starters, the whole internet is made of mark-up languages, with as best well-know example the html format. And these are more common than some would believe. R Markdown is a so-called mark-up language.
