bedrock 0.1.20

• 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.

bedrock 0.1.17

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

bedrock 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).

bedrock 0.1.9

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”.
