dataSDA v0.2.6

dataSDA v0.2.6 — minor update of the CRAN package (previous CRAN version 0.2.5).

R CMD check --as-cran (R 4.6.0, Windows): 0 errors | 0 warnings | 0 notes.

New features

• check_zero_width_intervals() — diagnostic that flags zero-width
  intervals (min == max) in interval-valued data. Accepts both MM format
  (paired _min/_max columns) and RSDA format (symbolic_tbl with
  symbolic_interval columns). Returns (invisibly) a logical scalar carrying
  a "flagged" matrix and a "variables" vector, and warns by default.
  A tol argument allows near-zero widths to be flagged. Useful for screening
  data before tools that divide by interval width (e.g.
  ggInterval::ggInterval_indexImage()).

• aggregate_to_symbolic(type = "int") gains a zero_width argument
  controlling how zero-width intervals in the aggregated output are handled:

  • "keep" (default) — leave the output untouched; zero-width intervals
    are returned as-is, with no removal, no adjustment, and no warning.
  • "remove" — drop every concept containing a zero-width interval.
  • "regenerate" — re-run the aggregation until none remain (stochastic
    group_by only).
  • "adjust" — add a small epsilon to each zero-width upper endpoint.

  A companion epsilon argument sets the adjustment amount. For "remove"
  and "adjust", a single warning names the affected variables and the action
  taken.

Other changes

• environment.mix: the four modal columns are restored to proper
  symbolic_modal vctrs so the object matches ggInterval::Environment in
  class and format; documentation updated accordingly. Regeneration script
  added under data-raw/.
• Vignette polished (subtitle, ggInterval plotting calls, v0.2.6 citation).
  The eval = NOT_CRAN gate keeps the CRAN vignette build fast (code-only);
  full evaluated renders are attached below as assets.
• Stopped tracking generated inst/doc/ artifacts so built tarballs no longer
  ship orphaned vignette figures.

See NEWS.md for the complete changelog.
