Changes in version 0.1.4 (2026-05-05)                  

New features

  - generate_crosstab() gains multiple_columns and
    multiple_columns_filter arguments. When multiple_columns = TRUE
    (requires at least 2 columns in ...), each column is treated as a
    binary indicator: rows where the column equals
    multiple_columns_filter (default 1L) are counted per x category and
    presented as side-by-side frequency/percent columns in a single wide
    table. All grouping options (group_as_list, calculate_per_group,
    group_as_hierarchy) are supported.
  - generate_crosstab() gains a multiple_columns_type argument (default
    "default"). When multiple_columns = TRUE and multiple_columns_type =
    "stacked", the columns supplied in ... are combined as a two-level
    hierarchical pivot: each level-1 category gets a subtotal column
    pair (frequency + percent), and the level-2 categories produce
    individual column pairs beneath it. Column labels follow the pattern
    "Frequency__<level-1 label>__<level-2 label>". The top-level spanner
    groups all frequency columns first, followed by all
    percent/proportion columns.
  - generate_output() now produces HTML (via the gt package) and PDF
    outputs, with proper spanner/header handling for cross-tabulated
    tables and consistent numeric formatting matching the XLSX output.
  - generate_frequency() and generate_crosstab(): setting both
    group_as_list = TRUE and group_as_hierarchy = TRUE now returns a
    nested named list with a grand-total entry at each level (no
    warning). The total entry key is formatted as "{var_label}:
    {label_group_hierarchy}". Previously, group_as_list was silently
    overridden with a warning.
  - Facade unification across formats: The facade system (add_facade(),
    get_tsg_facade()) now applies consistently across XLSX, HTML, and
    Word output. get_tsg_facade(which = "html") and get_tsg_facade(which
    = "docx") load format-specific defaults from new built-in YAML files
    (inst/extdata/facade/html/default.yaml,
    inst/extdata/facade/docx/default.yaml). Per-table add_facade()
    overrides are merged into all output formats automatically.
  - resolve_facade() gains a which argument for format-aware fallback
    when resolving user overrides.
  - gt_apply_facade() (HTML renderer) now supports the full cross-format
    key set: body.*, header.*, spanner.*, col_first.*, col_last.*,
    row_group.*, source_note.*, footnotes.*, border_outer.*,
    border_header.*, and table.lastRowBold.
  - tsg_to_flextable() (Word renderer) gains full facade key coverage
    with flextable-native styling.

Bug fixes

  - Fixed get_tsg_facade() throwing object 'facade_path' not found when
    called with a named facade that does not exist in the built-in YAML
    directory (#9).
  - Fixed sort_except in generate_frequency() being applied only to the
    first variable when two or more variables are supplied (#8).
  - Fixed incorrect cumulative frequency and percent/proportion values
    when position_total = "top" in generate_frequency() — cumulative
    columns are now set to NA for the total row when it is placed at the
    top (#6).

Documentation

  - All four vignettes rewritten for clarity and accessibility:
    goal-oriented section headers, plain-English introductions, and
    motivation-before-mechanics structure throughout.
      - Getting Started with tsg (was: Introduction)
      - Saving and Sharing Your Tables (was: Generating Outputs in
        Different Formats)
      - Customizing How Your Tables Look (was: Customizing Output with
        Facade)
      - Grouped Tables and Side-by-Side Comparisons (was: Advanced
        Features)

Internal changes

  - Refactored generate_frequency() and generate_crosstab() to remove
    self-recursion. Both functions now use extracted
    freq_compute_group() and crosstab_compute_group() helpers with a
    nest/map/unnest approach, eliminating duplicated pipeline code and
    improving maintainability.
  - Added internal helpers val_to_group_key() and
    build_nested_group_list() to support recursive nested-list
    construction.

                 Changes in version 0.1.3 (2026-02-28)                  

  - Fixed bugs when generating table using character labelled/factored
    variables.

                 Changes in version 0.1.2 (2026-02-22)                  

Features

  - Added experimental feature with an option to include grand total
    when generating tables with grouping for both generate_frequency()
    and generate_crosstab()
  - generate_crosstab() now allows 1 or more variables to be specified
    in the x argument for hierarchical grouping.
  - Added <- back hyperlink in the generated Excel output when table
    list is included.

Bug fixes

  - Fixed issues when generating a cross tabulation with NA values

                 Changes in version 0.1.1 (2026-02-12)                  

Features

  - Implemented new way of adding facade to the generated Excel output.
  - Added generate_template() for generating facade and table-list
    templates.

Bug fixes

  - Fixed column type consistency when generating top_n frequencies.

                 Changes in version 0.1.0 (2025-11-09)                  

  - Initial CRAN submission.
