fishglobr (perhaps to be renamed to fishglob) is an R package for efficiently downloading, caching, and querying the FishGlob database. FISHGLOB is an international consortium of scientists, experts and data providers who collect, curate, standardize, share and analyse data from scientific bottom trawl surveys.
You can install the development version of fishglobr like so:
pak::pak("fishglob/fishglobr")First we load the package and download and install the database locally. We only have to do this once. The data is stored in a local DuckDB database.
library(fishglobr)
