Lots of people have written talking about how wonderful markdown is, e.g. Increasingly, I use markdown for most of my note taking and report writing. And because it uses Plain text, the files are small and easy to edit on a variety of devices.Īs scientists we write a lot, not just papers, but also notes, code, emails, reminders, to do lists, blog posts etc. But unlike html, rtf, latex, or pretty much any other markup text, markdown is very readable, as is. In practice, it is a simple set of formatting commands applied to a plain text document that can be easily converted into fancy formatted html, pdf or word docs. Markdown’s goal is to be “ as easy-to-read and easy-to-write as is feasible”. The start of this process is the markdown language. Together, these provide a powerful tool set for scientists looking to save time and do reproducible research. It’s also now possible to weave your interpretation (stage 4) in with your R code (stage 2) and results (stage 3), to produce nice, self-contained and reproducible reports. Thankfully, there now exists a much nicer way to write reports, using the wonderful package knitr, a simple text-markup language called markdown, and the universal document conversion program called pandoc. the report cannot be regenerated without doing it all that copying and pasting over again.Word documents can’t be tracked (very well) under version control.Word doesn’t offer syntax highlighting, so it’s hard to read code presented this way,.your interpretation is separated from your code.lots of time wasted, plus copy and pasting sucks.That works, but there several downsides to this approach: Traditionally, most biologists do stages 2 and 3 in R, then fire up Word or Powerpoint and copy-paste everything for stage 4. These include all the preliminary results, weekly updates, emails with figures, and simply one’s own note taking, written during the lifespan of a project. Large reports like papers, are rare, but we write smaller reports all the time. As scientists, we write many reports, both small and large. These elements come together in the form of a report. Text, interpreting the figures and results, and describing the methods.Figures and tables generated by the code.These tools will help you communicate your science, and hopefully mean that you never copy and paste your R output again.Īs a start, let’s review the key components to any good analysis: What do you do? In this guide, we want to show you how to write nice, reproducible reports using some of the fantastic, free tools and packages that are now on offer. So you have some code, data and a cool result, now it’s time to communicate this with your collaborators (or supervisor). Writing reproducible reports in R with markdown, knitr and pandoc
