In contrast, with a reproducible document, you can just rerun with a tweak to the code. That’s a bad thing! It means you have an incentive to be lazy and to avoid redoing your stuff. At least one of us used to tweak tables and figures by hand constantly, leading to a major incentive never to rerun analyses because it would mean re-pasting and re-illustratoring all the numbers and figures in a paper. This is actually a really big neglected one for us. To create spiffy documents that can be revised easily.
MAKE AN RMARKDOWN GITHUB RENDABLE CODE
Creating a document that literally specifies where all the numbers come from in terms of code that operates over the data removes all this ambiguity. Even if you don’t have errors, it can still be very hard to recover the numbers from published papers because of ambiguities in analysis. Computational reproducibility means that other people can take your data and get the same numbers that are in your paper. To promote computational reproducibility. Nearly half of all papers had errors in them. Springer: 1205–26.) found that over 10% of p-values in published papers were inconsistent with the reported details of the statistical test, and 1.6% were what they called “grossly” inconsistent, e.g. difference between the p-value and the test statistic meant that one implied statistical significance and the other did not. “The Prevalence of Statistical Reporting Errors in Psychology (1985–2013).” Behavior Research Methods 48 (4). ( ⊕ 2016 Nuijten, Michèle B, Chris HJ Hartgerink, Marcel ALM van Assen, Sacha Epskamp, and Jelte M Wicherts. Using an automated method for scraping APA-formatted stats out of PDFs, Nuijten et al. There are more, but these are convincing to us. To be right, to be reproducible, and to be efficient. There are three reasons to write reproducible papers.
Now we’re together trying to help spread the word, because it can make writing manuscripts so much easier! We wrote this handout in RMarkdown as well (looks really sweet, no?).Ĭool, thanks for sticking with us and reading up through here! 2 2 Note: this is also possible for Python and other open-source data analysis languages, but we focus on R. In short: RMarkdown allows you to create documents that are compiled with code, producing your next scientific paper. The tutorial is based on documents that both Chris and Mike wrote independently (see here and here if you’re interested).

This document is a short tutorial on using RMarkdown to mix prose and code together for creating reproducible scientific documents.
