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.

What is relialearnr?

The teaching arm of an R reliability suite keeps pace with whatever its analysis siblings ship.

ReliaLearnR is a set of interactive learnr tutorials for reliability engineering, covering life data analysis, reliability testing, RAM concepts, reliability block diagrams, and repairable systems, each with code exercises and quiz questions. It was WeibullR.learnr until the start of 2026, when the rename and a set of shorter function names arrived together. A companion book now supplements the interactive material.

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.

ANALYTICS
0.0

The teaching arm of an R reliability suite keeps pace with whatever its analysis siblings ship.

◆ Current state

ReliaLearnR is a set of interactive learnr tutorials for reliability engineering, covering life data analysis, reliability testing, RAM concepts, reliability block diagrams, and repairable systems, each with code exercises and quiz questions. It was WeibullR.learnr until the start of 2026, when the rename and a set of shorter function names arrived together. A companion book now supplements the interactive material.

◆ Where it's heading

The tutorials track the maintainer's analysis packages rather than leading them: repairable systems and mean cumulative function teaching material appeared once the modelling functions for them existed elsewhere in the suite, and the reliability testing tutorial followed the same pattern earlier. Recent work has been about depth rather than coverage — interactive parameter sliders, goodness-of-fit sections, model comparison exercises, more quiz questions per topic. The rename to ReliaLearnR was part of the same suite-wide repositioning away from Weibull-specific branding that the plotting package made.

◆ Prediction

On the established pattern, the next tutorials will follow whatever the analysis packages shipped most recently; the entries do not indicate whether the newer tool-server interfaces will get teaching material of their own.
