Resources

I have included a handful of links to papers, software packages and tutorials/manuals about some tools I mention in my talk. Pull requests or issues on additional ones to include are welcome.

Research Compendia

• Statistical Analysis and reproducible research
• Packaging Data Analytical Work Reproducibly Using R (and Friends) (OA preprint). A practical introduction to setting up a research compendium in R.
• The rOpenSci reproducibility guide Slightly dated but still very useful

Examples of Research Compendia on GitHub Below are a few links to real world examples of research compendia in R. To have a minimal compendium, all you really need is a valid DESCRIPTION file containing a handful of fields such as type, name, version and dependencies. See Marwick et al 2017 for a detailed description of the different types of compendia.

Small

• Code and data associated with Duffy, James, and Longworth Applied and Environmental Microbiology paper describing the ecology, virulence, and phylogeny of a brood parasite of Daphnia, Blastulidium paedophthorum;

Medium

• Resolving the measurement uncertainty paradox in ecological management

Large

• Non-parametric Bayesian Inference for Conservation Decisions

• Find various other compendia on Github and Zenodo using the research-compendium tag.

Software packages related to research compendia

• 📦 rrtools by Ben Marwick (also the author of the packaging data analysis paper mentioned above) extends functions in devtools and provides instructions, templates, and functions to make a basic compendium suitable for doing reproducible research with R.
  • Also see 📦 workflowr by John Blischak and the task view on R-based data analysis projects maintained by John Blischak, Anna Krystalli, Ben Marwick, Daniel Nüst.
• 📦 usethis Many of the major function in rrtools are imported from usethis. A savvy user can get by setting up and maintaining a compendium purely with usethis functions.
• 📦 goodpractice - Designed to help you build more robust packages, the package does a deep dive on your package contents and provide advice on syntax pitfalls to avoid, code formatting suggestions, and helps you improve overall package structure.
• The 📦 rticles package by JJ has numerous journal templates and together with Rstudio addins like word countaddin and citr + knitcitations.

📈 Data management

• 📦 piggyback, [docs]: This clever R package allows you to attach arbitrary data (or other) files (upto 2gb each) to a GitHub release. Given GitHub's fast CDN, this would be an easy way to quickly attach large files to a compendium and read them back in a local/collaborator/remote environment very easily. As always be sure to archive a long-term copy on Zenodo.
• 📦 arkdb [docs]: This package allows you to archive and unarchive databases as flat text files.
• 🎥 For more on setting up data packages, see this excellent talk by Noam Ross at New York R.

Computational environments: Binder and friends

• My Binder is a free binderhub deployment that turns any Git repo into a collection of interactive notebooks. Now with better R support!
• For instructions on how to set this up for your R project, see my notes here
• Introducing Binder 2.0 — share your interactive research environment Paper describing the architecture of Binder in case you were interested in what was happening under the hood
• 🎥 A talk about Binder at Scipy 2018. Also see conference proceedings PDF.
• repo2docker A Python module that will turn any repo (or local folder) into a Docker Image.

Other hosted Binder hubs

• Pangeo binder Pangeo encourages everyone to use it.
• gesis
• Syzgy Binder + JupyterHub for Compute Canada

Setting up Binder for your analysis

I have captured all the various ways to set up mybinder with a R project in a separate document.

Are you interested in setting up or hosting a binderhub for the R community? Get in touch via the issues.

Also see

• Whole Tale
• Computing environments for reproducibility: Capturing the “Whole Tale” - OA paper describing the Whole Tale project.
• Code Ocean - A commercial, blackbox, full-stack service that will accomplish something similar to the above two projects. Code Ocean links will likely start appearing in papers soon.

Software packages related to setting up computational environments

• 📦 Containerit. Detailed blog post This sweet package will generate a Dockerfile for you by examining the code inside a folder or just from your session info. This is analogous to repo2docker but is very R centric
• stevedore Although there are a few docker clients (docker, harbor), this is my recommendation for managing docker containers from inside R.

🔨 Workflows: drake and friends

• 📦 drake - An R-focused pipeline toolkit for reproducibility and high-performance computing. Install the package from here or CRAN.
• The prequel to the drake R package A blog post by the creator of drake describing his motivation for the package.
• drake manual A detailed bookdown guide on how to setup and use drake for projects of varying levels of complexity.
• Presentation on drake Slides from a talk by Will Landau (who is here at the conference so go pick his brain if you want to learn more!)

Real world drake examples

• Pathogen modeling study

Miscellaneous

• IKEA diagram inspired by IDEA instructions
