Modelling the economic effects of reducing the demand for unhealthy commodities: An input-output approach - code and data repository

Introduction

The purpose of this repository is to provide reproducible code and data inputs to produce the results of the paper “Modelling the economic effects of reducing the demand for unhealthy commodities: An input-output approach”

Data Requirements

All data inputs required are available as part of the R package cdohio.mod, which is open source and available on GitHub here.

Usage

Fork the project on GitHub to create your own repository. This project uses renv to aid reproducibility of results by ensuring users make use of the same environment.

When a new user first launches in this project, renv should automatically bootstrap itself, thereby downloading and installing the appropriate version of renv into the project library. After this has completed, they can then use renv::restore() to install the project library locally on their machine.

Once the project library is restored, the repository is ready to be used to replicate the analysis once the requirements below are met.

The R scripts which reproduce the analysis are stored in the src/ directory. The script run_analyses.R in the top level of the repository is a meta-file which runs all of the R scripts in order. The key outputs are saved to outputs/.

Reproducibility

Note that this repository uses the renv R package to produce a reproducible environment for this analysis. see the package website for more information.

When first launching the project, the function renv::restore() will populate the renv/library folder, installing the R packages saved in the lockfifle.

The lockfile renv.lock is in the top level of the repository, and contains the metadata for all R packages used in the project. The libraries themselves are ignored by git and not uploaded to GitHub, and so a new user needs to install the packages themselves using the metadata.

The .Rprofile file in the top level of the repository is automatically run when the project is opened and this runs the script file renv/activate.R to set the renv folder as the source R package library.

The version of R used to produce the analysis is 4.4.1.
