Overview of invasimap functions

Quantifies and visualises invasion fitness from occurrence and trait data. Computes trait centrality, maps trait dispersion, and estimates interaction strength. Assesses site-level invasibility and community openness to new invasions. Produces interaction matrices and trait-specific invasion risk indicators. Aligns with Hui et al. (2023): integrates traits, propagule pressure, and environment.
