ggforestplotR 0.5.0

Breaking Changes

• Removed the deprecated grouping and grouping_strip_position arguments from ggforestplot(). Use facet and facet_strip_position instead.

Major Changes

• Added add_favors() for composing two-sided directional arrows and labels beneath the forest-plot panel. The fixed-height footer respects log scales, custom limits and expansion, and remains aligned when used after add_forest_table() or add_split_table().
• Added explicit subgroup mappings for mixed hierarchical displays, allowing standalone covariates and contiguous categorical blocks to share a forest plot. Subgroup p-values can be delegated as “overall” or “level” via p_method in tidy_forest_model() (#11)
• Added covariance-aware subgroup effects for fitted interaction models. tidy_forest_model() and fitted-model as_forest_data() methods now use marginaleffects to derive average slopes or comparisons from the original fit without refitting subgroup models or displaying raw interaction coefficients. Conservative automatic selection supports one continuous-by- factor interaction, while explicit selection supports factor comparisons and preserves additive, odds-ratio, ratio, and hazard-ratio scales.

Minor Changes

• Grouped values in add_forest_table() and add_split_table() now use the same vertical dodge as their plotted points, keeping table text aligned at different output sizes and with custom dodge_width values.
• Factor-valued group columns now retain their level order in legends, vertically dodged estimates, and aligned forest-table values.
• Deprecated term_header, n_header, events_header, and p_header in add_forest_table() and add_split_table(). Relabel displayed headers with the column_labels named vector instead.

ggforestplotR 0.4.0

Major Changes

• Added the forest_data S3 class as the package’s stable interchange format. It stores validated effect-scale, axis, confidence-level, reference-value, source-model, source-package, and source-column metadata. (#17)
• Converted as_forest_data() into an S3 generic with methods for data frames, existing forest_data objects, linear and generalized linear models, Cox models, and supported mixed-model classes. (#19)
• Refactored ggforestplot() to consume the forest_data contract instead of determining plotting behavior from the original model class.
• Added forest_metadata() for inspecting the semantic and provenance metadata associated with a forest_data object.

Minor Changes

• Separated the semantic estimate scale from the plotting-axis transformation. Ratio estimates now use estimate_scale = "ratio" and axis_transform = "log10"; unexponentiated log-link coefficients use estimate_scale = "log" and an identity axis.
• bind_forest_models() now returns forest_data and validates compatible estimate scales, axis transformations, reference values, and confidence levels before combining models.
• Fitted model objects and duplicate source data frames are not retained in forest_data; provenance records model classes, package names, and source column mappings instead.
• tidy_forest_model() remains available as a compatibility wrapper around the new as_forest_data() model methods.
• Legends positioned at the top or bottom are now collected at the patchwork level, centering them across the complete table-and-plot composition.
• Grouped tables now display model or group names in a dedicated, multiline column instead of prefixing every value. Include "group" wherever desired in columns, left_columns, or right_columns, and rename it through column_labels like any other table column.
• add_forest_table() now supports table_width and plot_width for controlling the relative widths of the two composed panels.

ggforestplotR 0.3.1

Minor Changes

• Fixed unintended behavior when passing custom columns to add_forest_table() specific to data-frame/plot inheritance.

ggforestplotR 0.3.0

Breaking Changes

• Removed the deprecated table-display shortcut arguments show_terms, show_n, show_events, show_estimate, and show_p from add_forest_table() and add_split_table(). Use columns, left_columns, and right_columns to choose table columns explicitly.
• Numeric table column positions now resolve against the supplied/source data columns in their original order, rather than the previous fixed built-in table-column order.

Major Changes

• Added mixed-model support for tidy_forest_model() and ggforestplot() when broom.mixed is installed. Mixed-model tidiers are restricted to fixed effects so random-effect parameter rows are not plotted as terms. (#21)
• Added confidence interval truncation support to ggforestplot() via ci_limits, with optional arrowheads for intervals extending beyond the displayed range. (#18)
• Added bind_forest_models() to stack multiple fitted models into one grouped forest-plot data frame. (#16)

Minor Changes

• Relaxed forest-data validation so only the core plot geometry columns term, estimate, conf.low, and conf.high are required. Optional table and grouping columns are validated only when used.

ggforestplotR 0.2.2

Minor Changes

• Faceted ggforestplot() output now respects factor level order in the facet column, allowing users to control facet ordering directly from their data.
• Fixed faceted ggforestplot() output when users add scale_y_discrete(limits = ...), preserving per-facet row filtering while accepting visible term labels. (#20)

ggforestplotR 0.2.1

Breaking Changes

• Simplified the reference-line API in ggforestplot(): ref_line now takes the numeric reference value directly, and NULL hides the line.
• Replaced the older reference-line arguments with ref_label, ref_linetype, and ref_color.

Major Changes

• Added facet and facet_strip_position as clearer names for grouped plot panels. The older grouping and grouping_strip_position arguments now warn and continue to work.
• Added linewidth for confidence interval widths. The older line_size argument now warns and continues to work.
• Added deprecation warnings for table-display shortcuts in favor of explicit columns, left_columns, and right_columns selections.

Minor Changes

• Added stripe_alpha to control row stripe transparency across plots, side tables, and split tables. (#7)
• Updated table helpers so they inherit custom y-axis ordering and filtering from the trained forest plot scale. (#9)
• Updated vignettes and tests to use the clearer faceting and geometry argument names.

ggforestplotR 0.2.0

Major Changes

• Added separate table formatting controls for point estimates, confidence interval bounds, and p-values via estimate_digits, interval_digits, and p_digits.
• Added ref_line, ref_line_value, and ref_line_label to standardize reference-line naming while keeping zero_line arguments backward compatible.
• Added term_labels, a named-vector relabeling helper for displayed model terms.
• Expanded add_forest_table(columns = ...) and split-table column selection to support arbitrary preserved data columns in addition to built-in columns.
• Added column_labels, a named-vector helper for relabeling displayed table column headers.
• Added a built-in ci table column and ci_fmt so users can display point estimates and confidence intervals in separate columns. conf.low and conf.high are accepted as aliases for ci.

Minor Changes

• Added model-aware default effect labels and scales, including odds ratios for binomial logit models and hazard ratios for Cox models.

ggforestplotR 0.1.1

Minor Changes

• Added events column support across ggforestplot(), as_forest_data(), add_forest_table(), and add_split_table(). (#2) (#3) (Thanks @sritchie73 for the suggestion)
• Added table header styling controls for font size, font face, and font family in both table helpers. (Thanks @sritchie73 for the suggestion)
• Split table composition code into dedicated source files to simplify maintenance of the public API.
• Refined split-table examples and documentation to match the expanded numeric column mapping.

ggforestplotR 0.1.0

Major Changes

• Refined split-table layout logic, including dynamic panel widths from column counts, alignment controls, and cleaner stripe/background handling.
• add_forest_table() now allows for custom column ordering via the columns argument.
• Converted package documentation to roxygen-generated NAMESPACE and .Rd files.
• Reworked package documentation, including pkgdown configuration, README installation guidance, and the vignette set.

ggforestplotR 0.0.0.9000

Initial development version

• Added grouped section support for forest plots.
• Added add_forest_table() and add_split_table() for plot-table composition.
• Added various plot and table customization options.
• Added package documentation, tests, and a getting-started vignette.
