In ScottKnott: The ScottKnott Clustering Algorithm

ScottKnott 1.4-0 (2026-05-14)

Bug Fixes

• m.infos.lmerMod() and m.infos.nest.lmerMod(): fixed a crash when emmeans returns asymptotic confidence interval columns (asymp.LCL/ asymp.UCL) instead of the df-based names (lower.CL/upper.CL). The CI column names are now detected dynamically at runtime.

New Features

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

Changes

• Removed the dependency on the doBy package. doBy::LSmeans produced unwanted side-effects in the console and in Sweave/knitr documents.
• Added the emmeans package as a dependency.
• All internal LSmeans calls have been replaced with emmeans.
• DESCRIPTION: added knitr, rmarkdown, and testthat (>= 3.0.0) to Suggests; set VignetteBuilder: knitr; added BugReports URL; removed the obsolete LazyLoad field.
• Demo files revised: corrected English, standardised argument style (dispersion= replaces the abbreviated di=), and fixed three bugs: duplicate variable sk4 in FE.R (renamed to sk5/sk6), spurious double comma in RCBD.R, and wrong variable name u_sk8 in CRD.R (renamed to u_sk4).
• All R source files reformatted to consistent 2-space indentation; mixed tabs and spaces eliminated throughout.
• xtable.SK(): treatment names moved from row names to an explicit Treatment column; added print.xtable.SK() S3 method that strips the inconsistent 2-space indentation inserted by print.xtable in all data rows except the first, which caused visible misalignment in compiled LaTeX and HTML tables.
• man/ files revised: English corrected, two files renamed (SPET.rd → SPET.Rd, LS.Rd → LSD.Rd), spurious \alias{SK.aov} removed, and demo(package='SK') corrected to demo(package='ScottKnott') in all documentation examples.
