Overview of contents

This repository is our research compendium for our analysis. The compendium contains all data, code, and text associated with the publication. The Rmd files in the analysis/paper/ directory contain details of how all the analyses reported in the paper were conducted, as well as instructions on how to rerun the analysis to reproduce the results. The data/ directory in the analysis/ directory contains all the raw data.

The supplementary files

The analysis/ directory contains:

• all the data files (in CSV format, in the data/ directory)
• the manuscript as submitted (in MS Word format)
• supplementary information source files (in R markdown format)
• executed versions of the supplementary files and all the figures that are included in the paper (in the figures/ directory)

The R package

This repository is organized as an R package. There are no actual R functions in this package - all the R code is in the Rmd file. I simply used the R package structure to help manage dependencies, to take advantage of continuous integration for automated code testing, and so I didn't have to think too much about how to organise the files.

To download the package source as you see it on GitHub, for offline browsing, use this line at the shell prompt (assuming you have Git installed on your computer):

git clone https://github.com/benmarwick/mjbtramp.git

Once the download is complete, open the mjbtramp.Rproj in RStudio to begin working with the package and compendium files.

The package has a number of dependencies on other R packages, and programs outside of R. These are listed at the bottom of this README. Installing these can be time-consuming and complicated, so we've done two things to simpify access to the compendium. First is the packrat directory, which contains the source code for all the packages we depend on. If all works well, these will be installed on your computer when you open mjbtramp.Rproj in RStudio. Second is our Docker image that includes all the necessary software, code and data to run our analysis. The Docker image may give a quicker entry point to the project, and is more self-contained, so might save some fiddling with installing things.

The Docker image

A Docker image is a lightweight GNU/Linux virtual computer that can be run as a piece of software on Windows and OSX (and other Linux systems). To capture the complete computational environment used for this project we have a Dockerfile that specifies how to make the Docker image that we developed this project in. The Docker image includes all of the software dependencies needed to run the code in this project, as well as the R package and other compendium files. To launch the Docker image for this project, first, install Docker on your computer. At the Docker prompt, enter:

docker run -dp 8787:8787 benmarwick/mjbtramp

This will start a server instance of RStudio. Then open your web browser at localhost:8787 or or run docker-machine ip default in the shell to find the correct IP address, and log in with rstudio/rstudio.

Once logged in, use the Files pane (bottom right) to navigate to / (the root directory), then open the folder for this project, and open the .Rproj file for this project. Once that's open, you'll see the analysis/paper directory in the Files pane where you can find the R markdown document, and knit them to produce the results in the paper. More information about using RStudio in Docker is avaiable at the Rocker wiki pages.

We developed and tested the package on this Docker container, so this is the only platform that We're confident it works on, and so recommend to anyone wanting to use this package to generate the vignette, etc.
