Changes in version 0.1.1 (2026-10-08)                  

Bug fixes

  - mdi_aggregate() no longer copies its input when it only summarises
    it (mrg = FALSE), and reads column types in place instead of copying
    the columns. Its peak memory on a large table drops from about 2.3
    to 0.6 times the table's size.
  - mdi_hier_apply() orders hierarchy levels by their number, so h_10
    comes after h_2 (they were ordered alphabetically).
  - mdi_clustering() with method = "pam" works again: it stopped with
    "length(labels) must equal nrow(Xmat)" whenever it was used.
  - mdi_clustering() with method = "mclust" works without mclust being
    attached (it stopped with "could not find function mclustBIC").
  - mdi_clustering() no longer changes the caller's random numbers: the
    seed it sets for reproducible clusters is undone when it returns.
    Clustering results are unchanged.
  - mdi_regress() computes confidence intervals with the requested
    covariance estimator (vcov), matching the standard errors.
  - mdi_make_conc() is rewritten: codes linked across years form one
    harmonized group (connected components), which removes the
    many-to-many join that stopped on large concordances. Each group is
    named after its smallest code in its latest year, with a D suffix
    when that year is before the last one. Group membership is
    unchanged; some group names differ from 0.1.0. year_list now
    defaults to the concordance's full year range, and a year without
    concordance rows is an error.

New features

  - mdi_import_data() reads tables from an Oracle database (format =
    "oracle"), through RODBC with the password asked interactively
    (askpass); both packages are suggested, not required.
  - mdi_aggregate() and mdi_jointdist() take domVar and domNr for the
    dominance check, and mdi_jointdist() takes minNumObs.
  - mdi_outlier() accepts several grouping variables in group.
  - check_dt(), check_string(), check_choice(), check_char_vec() and
    hier_levels() are exported, for packages that build on mditools.

Documentation

  - Help pages use Markdown; panel_lag() and panel_lag_L() are
    documented.
  - Acknowledgements and the EU funding statement (Technical Support
    Instrument, project ProdTool) in the README and on the package help
    page; the European Union is listed as funder.
