TukeyC 1.4-0 (2026-05-23)

New Features

Added a basic testthat test suite covering TukeyC with formula, aov, and lm inputs for balanced and unbalanced designs, as well as summary, print, plot, and xtable methods.
Added two vignettes: TukeyC_intro (HTML, via R Markdown) and TukeyC_intro_pdf (PDF, via knitr/LaTeX), covering quick start, accepted input classes, unbalanced data, RCBD, factorial and split-plot designs, visualisation options, tabular output, and mixed models.

Bug Fixes

make.TukeyC.groups(): refactored letter-grouping with sequential scanning and homogeneity checks for non-transitive pairwise patterns under unbalanced designs; added tests/testthat/test-make-TukeyC-groups.R.
make.TukeyC.test(): Result table now uses a named Means column combined with letter columns from make.TukeyC.groups().
m.infos.lmerMod() and m.infos.nest.lmerMod(): detect emmeans CI column names dynamically (lower.CL/upper.CL or asymp.LCL/asymp.UCL).
summary.TukeyC(): corrected message typo (“Groups” vs “Goups”).
Demos and plot.TukeyC documentation: di= / disp= replaced with dispersion=.

Changes

README.md fully rewritten: badges (CRAN status, downloads, checks, lifecycle, licence), key features, installation instructions (CRAN and GitHub), quick-start examples, project layout, contributing guide, and roadmap.
DESCRIPTION: version bumped to 1.4-0; author fields standardised to match the ScottKnott package template; R (>= 4.0.0); added BugReports URL and LEC software page; added knitr, rmarkdown, and testthat (>= 3.0.0) to Suggests; set VignetteBuilder: knitr and Config/testthat/edition: 3.
Added NEWS.md (this file), migrated from the historical ChangeLog.
plot.TukeyC(): removed the none dispersion option; default is now mm (min–max range), matching plot.SK().
xtable.TukeyC(): treatment names moved from row names to an explicit Treatment column; added print.xtable.TukeyC() S3 method that strips the inconsistent 2-space indentation inserted by print.xtable in compiled LaTeX and HTML tables.
All R/ source files reformatted for consistent 2-space indentation, spacing around operators, and readable line breaks; mixed tabs and trailing whitespace eliminated throughout.
man/: author fields standardised to scientific name order (Faria, J. C.; Jelihovschi, E. G.; Allaman, I. B.), matching the ScottKnott package.
Removed ChangeLog; release history is maintained in NEWS.md only.
DESCRIPTION: LazyData: true (replacing LazyLoad).
Re-export xtable() from xtable; added man/xtable.Rd.
Internal helpers in R/tukeyc-utils.R for nested filters, emmeans CI columns, error-term renaming, and interaction labels; removed eval(parse()) from nest/boxplot code paths.
TukeyC.lm() and make.TukeyC.groups(): ifelse() side effects replaced with if blocks.
Removed obsolete commented code (doBy, parallel).
Expanded testthat coverage (test-tukeyc-extra.R: groups, boxplot, FE nest, xtable export).
English language review across the package: Portuguese comments in R/ translated to English; grammar and spelling corrected in man/, demo/, and README.md (user-facing text and examples).

In all functions returning an LSmeans object, replaced aux_mt$coef[,1] with with(aux_mt, estimate).
In boxplot.TukeyC and plot.TukeyC, replaced par(mar = op) with on.exit(par(mar = np)) to restore graphics parameters reliably.
