The energetics of fish growth and how it constrains food-web trophic structure

This repository contains code and data needed to reproduce the article:

Barneche DR, Allen AP The energetics of fish growth and how it constrains food-web trophic structure. Ecology Letters. doi: 10.1111/ele.12947.

Instructions

All analyses were done in R. To compile the paper, including figures and tables we use the remake package for R. You can install remake using the devtools package:

devtools::install_github("richfitz/remake", dependencies=TRUE)

(run install.packages("devtools") to install devtools if needed.)

The remake package also depends on storr, install it like this:

devtools::install_github("richfitz/storr", dependencies=TRUE)

Next you need to open an R session with working directory set to the root of the project.

We use a number of packages, missing packages can be easily installed by remake:

remake::install_missing_packages()

And then install the package fontcm, via extrafont. This installs the font CM Roman we use in our figures (for more information on see these instructions:

extrafont::font_install('fontcm')

Then, to generate all figures, analyses, and tables, simply run:

remake::make()

All output will be automatically placed in a directory called output (it is going to be automatically created for you).

Also notice that the Bayesian analysis in this paper might take a couple of days to run on a regular computer.

If you find remake confusing and prefer to run plain R, you can use remake to build a script build.R that produces a given output, e.g.

remake::make_script(filename="build.R")
