Changes in version 0.1.0 (2026-08-08)                  

  - Initial CRAN release.
  - Ported from the community-contributed Stata package (pathintdid.ado,
    pathintdidplot.ado, pathintdidrobust.ado) to R.
  - pathintdid(): cumulative causal effect (sigma), path-integrated ATT
    (tau-bar), and conventional static DiD, with cluster-style standard
    errors, t-tests, and confidence intervals.
  - pathintdidplot(): two-panel base-graphics visualization of the
    treated/counterfactual paths and the running cumulative effect.
  - pathintdidrobust(): dynamic placebo test for pre-treatment parallel
    trends, grid-density/quadrature-scheme sensitivity check, and
    anticipation-robust bounding estimator.
  - Bundled example data set trainingpanel.
