What is brglm2?

A bias-reduction package reaches 1.0 by adding an estimator built for high-dimensional logistic regression

brglm2 fits generalized linear models using mean and median bias reduction rather than plain maximum likelihood, which matters most when ML estimates are infinite or badly biased. The 0.7-0.9 line broadened coverage — negative binomial via brnb(), ordinal superiority measures, the expo() method for exponentiated parameters, add1()/drop1() so step() stops silently producing nonsense. Version 1.0.0 in August 2025 added mdyplFit(), estimating logistic regression by maximum Diaconis-Ylvisaker prior penalized likelihood with optional high-dimensional corrections. The two releases since have tuned that new path.

What is piecepackr?

A board game graphics package runs one of the most disciplined deprecation cycles in R.

piecepackr renders game pieces — piecepack, chess, dominoes and related systems — as 2D grid graphics, 3D meshes, animations, and print-and-play PDFs. Its interface is mature enough that most releases are about managing change rather than adding capability: features get deprecated with a named replacement, live through a release or two, then get removed on schedule. The current release completes the cycle opened a year earlier, retiring the new_device and style arguments in favour of open_device and the composable font, border, background_color and edge_color set.

A bias-reduction package reaches 1.0 by adding an estimator built for high-dimensional logistic regression

◆ Current state

brglm2 fits generalized linear models using mean and median bias reduction rather than plain maximum likelihood, which matters most when ML estimates are infinite or badly biased. The 0.7-0.9 line broadened coverage — negative binomial via brnb(), ordinal superiority measures, the expo() method for exponentiated parameters, add1()/drop1() so step() stops silently producing nonsense. Version 1.0.0 in August 2025 added mdyplFit(), estimating logistic regression by maximum Diaconis-Ylvisaker prior penalized likelihood with optional high-dimensional corrections. The two releases since have tuned that new path.

◆ Where it's heading

The package's older work assumed the classical regime where observations comfortably outnumber parameters. mdyplFit() and its hd_correction argument target the opposite case, and the follow-up releases are almost entirely about it — Pearson residuals on original responses, aliased parameter handling, the sloe() signal-strength estimator ignoring leverage-one observations. Meanwhile the older surface gets graceful-failure work: brglm_fit() now returns its latest estimates with warnings rather than aborting.

◆ Prediction

Given that 1.0.1 and 1.1.0 are both dominated by mdyplFit follow-ups while the classical path receives only robustness fixes, further work on high-dimensional corrections is the likeliest direction.

A board game graphics package runs one of the most disciplined deprecation cycles in R.

◆ Current state

piecepackr renders game pieces — piecepack, chess, dominoes and related systems — as 2D grid graphics, 3D meshes, animations, and print-and-play PDFs. Its interface is mature enough that most releases are about managing change rather than adding capability: features get deprecated with a named replacement, live through a release or two, then get removed on schedule. The current release completes the cycle opened a year earlier, retiring the new_device and style arguments in favour of open_device and the composable font, border, background_color and edge_color set.

◆ Where it's heading

Two things dominate the log. The first is that deprecation discipline, unusually explicit for a package this size — every removal names its successor, and deprecations announced in one release are removed in a predictable later one. The second is defensive dependency management: version bumps pinned around bugs introduced upstream in rayrender and rayvertex, a warning class for known-buggy cairo versions with an option to suppress it, and suggested packages required for metadata embedding with clear messages when they are absent. Functionality still arrives — vectorised 3D object export that finally handles composite pieces, new crosshair grobs, a reworked colour palette — but it arrives inside that maintenance rhythm rather than driving it.

◆ Prediction

The features deprecated in this release — the preview_layout component and the 4x6 print-and-play size — are on the established path toward removal in a future version, with the documented ppdf-based replacement already in place.
