A first reason is that as you begin your R programming adventures, you’ll quickly learn that no “right” answer for implementing R code to meet an analysis objective exists. However, I now require RMarkdown as the means for evaluating coursework. MS PowerPoint or Word have been the most common. Historically, I’ve accepted just about any format for answers to exercises, quizzes, and tests in courses Iteach.
Hopefully some of the advantages as outlined above answer this question.īut another, pragmatic reason relates to classes, especially mine. From this point forward I’ll call documents integrating R coding RMarkdown documents so as to distinguish them from other types of Markdown documents. However, command–line code from Plain Vanilla R, which is still used by Curmudgeonly Dinosaurs like me, can also be used to generate Markdown documents. It can be, for all intent and purpose, your research metadata.Īlthough not a necessary requirement, it is easiest to configure and generate Markdown output from within RStudio.

Think about this for a moment in your role as a research scientist: By using Markdown you can fully replicate the analytical processes that underlay your research, showing the code you employ, the output it generates, be it numeric or graphical, plus text explanations about the analytical processes of your work. This is addition to the text formatting mentioned above. In the case of R, and Markdown as an example of a document Markdown language, it provides a means to embed - and actually run - R code from within a single document, all using simple syntax coding. html format for browsers or many different text formats. Formats are fairly flexible, including output in. You “markdown” text, including, for example, document formatting such as boldface, headers, lists, and mathematical symbols and equations, pictures, links to other files or webpages - in short, just about anything you see on a webpage, journal article, or book, can be constructed using Markdown. It evolved as means to embed formatting syntax into a document and have it rapidly and easily converted to a desired format. Markdown still involves embedding additional elements into a document, but has a slightly different purpose. For example, by clicking the “REVIEW” tab on a MS Word document you initiate a “markup” process where a reviewer’s comments and editorial suggestions are shown on the document. A document markup language is a way to distinguish basic text from other document elements, such as those that occur during an editorial review.
If you remove them, it seems to render correctly.Markdown is a form of document markup language. While it might not seem obvious that a LaTeX limitation would impose itself on an HTML target, the rendering uses MathJax (javascript library) that renders LaTeX math mode. So it is not allowed in display math and it should never be used on the line before display math either, in that position it does not generate an error but forces TeX to take recovery action that produces a spurious white paragraph on the line above the display. It is an instruction exactly the same as the command \par which ends a paragraph and starts TeX's line breaking algorithm to split a paragraph into lines. From Īn empty line in TeX should never be used just to arrange the source.
