pc: Pattern Causality Analysis

Unveil interactions in complex systems through pattern causality analysis (PC), with the original algorithm for time series data by Stavroglou et al. (2020) <doi:10.1073/pnas.1918269117>, as well as methodological extensions for spatial cross-sectional data introduced by Zhang & Wang (2025) <doi:10.1080/13658816.2025.2581207>, together with a systematic description detailed in Lyu et al. (2026) <doi:10.1016/j.compenvurbsys.2026.102435>.
