Provides tools for analyzing spatial cell-cell interactions based on ligand-receptor pairs, including functions for local, regional, and global analysis using spatial transcriptomics data. Integrates with databases like 'CellChat' < https://github.com/jinworks/CellChat>, 'CellPhoneDB' < https://www.cellphonedb.org/>, 'Cellinker' < https://www.rna-society.org/cellinker/>, 'ICELLNET' < https://github.com/soumelis-lab/ICELLNET>, and 'ConnectomeDB' < https://humanconnectome.org/software/connectomedb/> to identify ligand-receptor pairs, visualize interactions through heatmaps, chord diagrams, and infer interactions on different spatial scales.
