![]() 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. (If you want to go this route you can read more about ol tag attributes).Markdown is a form of document markup language. If it is important that your lists render as proper markup, you can still control the numbering of your lists by using markup in your markdown and using the reversed and start attributes on the ordered list tag ( ). Personally, I’m more than happy to give up this margin to get the rendering I want. we’re missing the margin that gets applied to lists). ![]() When we escape the period in our list items, we don’t actually get an HTML list instead we get text that looks like a list (e.g. The solution I’ve found is adding a backslash ( \) before the period, which disables the list auto-numbering. Often, I need to reference item 3 from an earlier list but if I write 3. I find this problem comes up a lot when I’m working with Issue tickets in Bitbucket or GitHub. However this will render with the numbers automatically generated. for a countdown in preparation for starting a run 3. Sometimes I need my numbers out of order, e.g. This is great because now if you need to re-order your list or insert an item you don’t have to re-number everything. Oneīecause the list is rendered as / markup, the leading number doesn’t matter. The markdown parser will automatically turned a numbered list like: 1. One of the features I have mixed feelings about, is auto-numbering of ordered lists in markdown. I spend most of my time doing my writing in markdown.
