Base R (version >= 4.0) and the RStudio IDE.

In the RStudio IDE, open the file messinian_db.Rproj. This opens the RProject of the same name, and should automatically install the renv package (if not already installed). First, run

renv::restore()

to install all required packages and their dependencies. Then run

source("code/download_data.R")

to download the latest version of the database from Zenodo. Then, run

source("code/make_table_and_plots.R")

in the console to produce the summary statistics of the database (stored in the variable table). You can view the values by running

table

in the console, and inspect the figures in figs/. Details on producing the map are given in the file code/make_maps.R.

• code : folder with R code
  • make_table_and_plots.R : script to generate table 1 and figures
  • make_maps.R : script to generate the maps
  • download_data.R : script to download data from Zenodo
• data : folder for raw data. Initially empty, will be filled with downloaded data after the script in code/download_data.R is run.
• figs : folder for figures. Initially empty
• renv : folder used by the renv package
• .gitignore : untracked files
• .Rprofile : session info
• messinian_db.Rproj : RProject file
• README : README file
• renv.lock : lock file for renv package
