Fig-fig wasp systems represent a widely applicable but underutilized framework for community assembly research, yet their multi-trophic structure and species interactions substantially increase the complexity of community simulation. We present figsimR, an open-source, modular R package that implements fig wasp community simulation via a single high-level function, simulate_figwasp_community(), with controllable mechanisms and reproducible workflows. The simulation runs at the individual-fig level and records species-specific wasp activity and outcomes, including but not limited to egg production, host-specific parasitism, final fig wasp emergence, seed production, flower availability, and ovule-resource use within each fig. The package also provides functions for calculating commonly used diversity and community-summary metrics, allowing fig-level community outputs to support downstream comparison and model diagnostics. We demonstrate a typical workflow-parameter setup, simulation, and metric calculation-on fig wasp communities associated with
