Changes in version 0.1.20 (2026-10-16)                 

  - toBaseR() gains a method for data.table: key, secondary indices and
    the internal self-reference are dropped, and a deep copy is
    returned. haven_labelled columns are converted to factors, as for
    tibbles.
  - toBaseR() on tibbles no longer breaks up list and matrix columns.

                       Changes in version 0.1.17                        

  - courseData() has been renamed to readCourseData(), which describes
    the function better.

                       Changes in version 0.1.15                        

  - resolveFormula(): subset now follows base R semantics (evaluated in
    data, as in lm()); new resolveFormulaFromCall() for formula methods.
    y ~ a:b is accepted as the cells of several grouping variables.
  - New conceptMap() and conceptAudit(); getConcepts() is now exported.
  - Fixed a test failing on macOS arm64 (CRAN M1mac).

                 Changes in version 0.1.9 (2026-09-29)                  

Initial CRAN release

  - First public release of bedrock, the base layer of the DescToolsX
    package suite: data manipulation and reshaping, predicates for data
    inspection, vector and string operations, labels and metadata, and
    routines from number theory and combinatorics.
  - Performance critical routines are implemented in C++ via Rcpp.
  - Documented in the vignette "Combinatorics".
