You can then experiment with, and learn to apply, more sophisticated aspects of RMarkdown to your documents.

There are many, many more options for creating RMarkdown documents, but the best approach to learning RMarkdown is to first learn how to build simple documents. The steps below will help you build a simple RMarkdown document. “How the **** did I actually do that analysis?!!?”Īn overview of the process from within RStudio You, the student, get a fully documented process by which you performed an analysis for future reference, a metaphorical trail of breadcrumbs by which you can answer the time-honored question all analysts eventually face: I get a consistent, easy-to-read and evaluate document that includes your R code, the results of that code, as well as the rationale for your R analytical pathway, and your interpretation of your results. The second reason is one of convenience for me as the instructor, and you as the student. Because one of the easiest ways for you to learn R is to see examples, RMarkdown documents provide a great way for me to post - and you to see - “clever” answers to R coding problems. Other students and colleagues, one of them being perhaps more clever, might find a more efficient approach to a R coding issue. You, as a student and researcher, will find a personal solution.

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. Markdown is a form of document markup language.
