TernTables 1.6.4

Bug fixes / CRAN compliance

Removed all uses of <<- in ternD(), ternG(), and ternP(). Counter and tracker variables are now accumulated via a local environment created with new.env(parent = emptyenv()) rather than super-assignment, which avoids unintended side-effects on parent frames (CRAN policy).
Replaced bare set.seed() inside ternG() with withr::with_seed() so the global RNG state is never modified (CRAN policy). Added withr to Imports.

CRAN resubmission addressing reviewer comments on v1.3.1.
All \dontrun{} blocks replaced with \donttest{} across all exported functions. Examples that write files to disk use \donttest{} because the ‘Word’ export operations may exceed 5 seconds on slower machines; no missing software or API keys are required.
Software and package names now quoted in the Description field of DESCRIPTION per CRAN policy: ‘Word’, ‘Excel’, ‘tibble’, ‘officer’, ‘flextable’, ‘writexl’, ‘rstatix’.
Package-level documentation (?TernTables) updated: normality routing description corrected to four-gate algorithm; .onLoad now explicitly initialises TernTables.line_break_header option.
val_format() now uses the Unicode plus-minus symbol (±) for consistency with ternG() and ternD() output.
utils_naming.R: single-word variable names (e.g. age, sex, race) now correctly flow through the abbreviation map and capitalisation rules in .apply_cleaning_rules().

Added odds ratio (OR) support for two-level categorical variables in ternG() (e.g. Male/Female shown with 1.00 (ref.) and computed OR with 95% CI). Previously only Y/N and 0/1 binary variables received ORs.
Added factor_order = "mixed" option to ternG() and ternD().
Post-hoc compact letter display (CLD) superscripts implemented in utils_posthoc.R with center-based letter ordering (highest center = “a”).
Fallback to Monte Carlo simulation for Fisher’s exact test when the exact algorithm cannot complete due to workspace limits (B = 10,000; seed fixed via getOption("TernTables.seed")).
Liberalized PHI column name detection in utils_preprocess.R to reduce false positives on common research variable names.

Integrated tern-tables.com web app into all public-facing documentation: README, vignette, and package help page (?TernTables).
Added URL: and BugReports: fields to DESCRIPTION.

Added ternP(): preprocessing function for raw CSV/XLSX data. Handles string NA conversion, whitespace trimming, empty column and blank row removal, and case normalisation. Hard-stops on PHI column name patterns and unnamed columns with data.
Added write_cleaning_doc(): writes a ‘Word’ audit document recording every transformation applied by ternP().
Added bundled example data tern_colon_messy.csv to inst/extdata/csv/ for use in ternP() examples.
line_break_header parameter refined: improved behaviour for edge-case column widths in ternG(), ternD(), and word_export().

Added ROBUST normality routing (consider_normality = "ROBUST", now the default). Four-gate algorithm applied per group: (1) n < 3 fail-safe to non-parametric; (2) |skewness| > 2 to non-parametric; (3) all groups n ≥ 30 to parametric via CLT; (4) Shapiro-Wilk p > 0.05 to parametric. Implemented in both ternG() and ternD().

Added ternB(): combines multiple TernTables result tibbles into a single formatted ‘Word’ document.
Added table_caption parameter to ternG(), ternD(), and word_export(): places a bold caption above the table in the ‘Word’ output.
Added table_footnote parameter to ternG(), ternD(), and word_export(): adds a merged footer row below the table.
Added Welch ANOVA for 3+ group continuous comparisons (parametric path); previously only Kruskal-Wallis was available for 3+ groups.
Added line_break_header parameter to ternG(), ternD(), and word_export(): wraps long column headers onto two lines in ‘Word’ output.
write_methods_doc() now generates a methods paragraph tailored to ternB() multi-table output.
Fixed bug where P values were not displaying in three-group comparisons.
Fixed dynamic bolding/non-bolding of table captions.

Initial CRAN submission.
ternG(): grouped comparison table for 2- and 3-level group variables, with optional odds ratios (OR_col), normality testing, and post-hoc test framework.
ternD(): descriptive summary table with no group comparisons.
word_export(): exports any TernTables tibble to a formatted ‘Word’ document.
write_methods_doc(): generates a boilerplate statistical methods paragraph.
val_format() and val_p_format(): formatting utilities for publication-ready numeric and P value display.
