Version 1.8.5

  • Added the LearnDis dataset (Tabachnick & Fidell, 2013, Table 7.1): a small 3 (Disability: Mild/Moderate/Severe) x 2 (Treatment/Control) factorial giving reading (WRAT_R) and arithmetic (WRAT_A) achievement scores and IQ, for worked MANOVA/MANCOVA examples and, in particular, a citable, hand-checkable example for the Roy-Bargmann stepdown analysis under development. Its Disability factor is ordered (Mild < Moderate < Severe).

  • Added the ReadingDisability dataset: 571 children classified into four reading-achievement groups (Severe/Mild/Average/Superior, an ordered factor) on six cognitive/achievement measures (PPVT, RD, EF, VF, VMI, SIM). Reconstructed by simulation from the group means, SDs, and pooled within-cells correlations in Bray & Maxwell (1985, Multivariate Analysis of Variance, Table 2.3).

  • Added traceCI(): analytic (Bai & Silverstein, 2004) confidence intervals for the trace (sum of eigenvalues) of one or more covariance matrices, complementing logdetCI() and eigstatCI().

  • Added stdmodel() and stdcoef() for standardized (“beta”) coefficients on lm/mlm objects: responses and numeric predictors are standardized, factor predictors are left raw. coefplot.mlm() gains a std = TRUE argument using this to plot standardized-coefficient confidence ellipses.

  • Added a live heplot3d() example to the HE_manova vignette’s MockJury section (ratings on phyattr, independent, and sophisticated), shown as a rotatable, zoomable 3D widget.

Maintenance

  • Clarified the coefplot.mlm() documentation to explain how it differs from car::confidenceEllipse()’s mlm method: coefplot() fixes a pair of responses as plot axes and overlays one ellipse per predictor, while confidenceEllipse() fixes a pair of coefficients and shows their joint confidence region.

  • Added an explicit rgl::rglwidget() call to heplot3d()’s example, so its pkgdown reference page shows an interactive 3D plot instead of nothing. rgl’s automatic pkgdown widget support only fires for a visibly-returned object of class rglId/rglOpen3d; heplot3d() returns a different class invisibly, so nothing triggered it without this explicit call.

  • Calling rgl::rglwidget() directly in a bookdown-based, as_is vignette (like HE_manova’s new example above) renders fine in a standalone vignette build but shows as a blank box on the pkgdown site: pkgdown replaces the <head> of the article page when assembling it, silently dropping the <script> tags the widget needs. The fix – pre-rendering the widget to a self-contained file and embedding it with an <iframe> instead – is documented in heplot3d()’s @details for reuse in other vignettes.

  • Fixed math rendering on the pkgdown site for all four as_is vignettes (HE_manova, HE_mmra, Robust, datasets): _pkgdown.yml never configured a math renderer, so $...$ expressions showed as literal text instead of typeset equations. Configured KaTeX (matching the working setup already used in the matlib package) after finding that MathJax’s CDN bundle doesn’t support \boldsymbol, needed for bold Greek letters like \boldsymbol{\beta} (\mathbf{} only covers Roman symbols, not Greek).

  • Bare/dollar-math H/E references to the hypothesis and error matrices (in heplot(), heplot1d(), heplot3d(), pairs.mlm(), etasq(), and the package overview) are now \eqn{\mathbf{H}}{H}/\eqn{\mathbf{E}}{E} – the earlier $\mathbf{H}$ form isn’t valid Rd and rendered as mangled literal text in plain ?fun help.

  • Modernized roxygen documentation across R/: legacy Rd macros (\code{}, \link{}/\link[pkg]{}, \pkg{}, \emph{}) converted to markdown syntax in 44 files, fixing two pre-existing broken links (missing-backslash typos) and two stale rgl link targets found along the way.

  • Reorganized vignette assets: images and figures moved from vignettes/fig/ to vignettes/images/, and four orphaned, unreferenced 2017-era images removed.

  • Dropped the hard Depends: broom for glance.mlm(); now Imports: generics (the lightweight package defining the glance generic, which broom itself depends on) instead, with broom moved to Suggests. glance() still works the same as before with just library(heplots).

Version 1.8.4

CRAN release: 2026-08-23

CRAN resubmission of v1.8.3, addressing two URL findings from the win-builder CRAN-incoming-feasibility check.

  • Fixed the NeuroCog documentation to cite the Nuechterlein et al. (2008) reference by DOI instead of a PubMed URL that CRAN flagged as needing an update. A win-builder dry run then flagged the replacement itself: CRAN wants bare doi.org links written with the \doi{} macro, not \url{}. Fixed that in NeuroCog, and found (and fixed the same way) two more pre-existing bare doi.org references in Iwasaki_Big_Five and TIPI’s documentation that hadn’t yet been flagged.

  • Withdrew vignettes/repeated-JSS.pdf (a static reprint of the published Journal of Statistical Software article, included via the R.rsp::asis engine) to vignettes-old/, rather than continue explaining its embedded non-canonical URLs to CRAN on every submission. Dropped the now-unused R.rsp from Suggests/VignetteBuilder.

  • Added a second, shorter worked example to the Robust.Rmd vignette using the robustbase::pulpfiber data (Rousseeuw et al. 2004): a multivariate multiple regression contrasted with the earlier Pottery MANOVA example, using the weight plot and an MCD-based distancePlot() to distinguish vertical outliers, a bad leverage point, and two good leverage points.

  • distancePlot() documentation now cross-links robmlm(), car::influencePlot(), and mvinfluence’s influencePlot.mlm() method; fixed verbose argument not actually gating the cutoff cat() line.

Version 1.8.3

This is a modest cumulative release of several versions since the last CRAN release (v 1.8.1)

  • Added a link to the NLSY97 Cohort Index in NLSY’s documentation.
  • Added pvPlot() for partial variable plots: visualizes the partial correlation between two variables after controlling for all others, as a scatterplot of the residuals from regressing each on the rest, enhanced with a data ellipse, regression line, and point labels for unusual cases. Similar in spirit to car::avPlots(), but works directly on a data frame rather than a fitted model.
  • Added cute 404 page for pkgdown
  • Added a general .release_checks.R script in the repo (but .Rbuildignored)

Version 1.8.2

This is a large cumulative release of several versions since the last CRAN release.
