intersimR provides tools to detect and quantify local interaction events between marine animals and vessels using tracking data. The package implements the simulation-based framework described in A simulation-based framework to detect marine animal-vessel interactions using tracking data, allowing users to evaluate attraction and following behaviour through null-model simulations and event-level metrics.
The package is designed to support reproducible analysis pipelines, making it easy to apply the framework to new datasets across marine species and vessel types.

Overview
intersimR includes tools for:
Extracting local interaction events from animal and vessel tracks
Generating simulation-based null models
Computing attraction and following behaviour
Estimating p-values based on repeated simulations
Summarising and visualising interaction events
The workflow mirrors the structure of the original methodological paper, with generic functions that can be applied to any time-synchronised animal–vessel tracking dataset.
