lagdynamics: Lag Sequential Analysis, Dynamics, and Lag Transition Networks

A modern, tidy, pipe-friendly toolkit for lag sequential analysis and lag transition networks of categorical event and sequence data. It provides an accessible, unified workflow for fitting, inspecting, visualising, and comparing lagged transition patterns, with tidy outputs throughout. Includes confirmatory tools for uncertainty, robustness, and group differences, including bootstrap intervals, analytic certainty, split-half reliability, case-drop stability, permutation tests, and Bayesian group comparisons. Supports long-format event-log import, import from common sequence and state-sequence objects, multi-lag analysis, structural-zero constraints, transition and initial probabilities, plotting of transition structures, and an experimental directed transfer-entropy measure (Schreiber, 2000) <doi:10.1103/PhysRevLett.85.461>. Numerical methods are implemented from primary literature and cross-validated against base-R primitives and hand-formula identities.
