seabirddietDB

The goal of seabirddietDB is to provide access and tools to interact with a database of seabird diets collected around the British Isles.

Installation

You can install the development version from GitHub with:

# install.packages("remotes")
remotes::install_github("annakrystalli/seabirddietDB")

For more details on the dataset, check out the full documentation

Example

To access the data simply load the package. The data is then available

A version with more formal data types/structures in the columns (ie geographic information stored as sf, categorical data as factors etc) is also available. Note that you will need package sf installed to load this version of the data.

filter prey

sbd_filter(prey_taxon = c("Cottidae", "Actinopterygii"))
