What is crane?

Crane is turning into the table-and-plot layer for Roche's clinical output stack.

Crane publishes release candidates rather than finals, and the whole of 0.3.2 is carried by a single rc2 body — its two sibling tags are one-line styling commits, one of them tagged with an unsubstituted vX.Y.Z placeholder. The rc2 notes run to dozens of additions across regression tables, line plots and hierarchical rate tables.

What is lifecontingencies?

An actuarial mainstay spends its releases on CI plumbing, not on new mathematics.

lifecontingencies is a long-running R package for actuarial life-contingency mathematics. Its three most recent tags show a maintainer keeping the infrastructure alive rather than extending the library: 1.5.2 is entirely author-metadata corrections, CI workflow repairs and release automation, 1.4.4 moved presentValue() onto Rcpp, and 1.4.1 states outright that it is identical to the version before it. The 1.5.2 notes jump from 1.4.4, so whatever happened in between never reached this feed.

Crane is turning into the table-and-plot layer for Roche's clinical output stack.

◆ Current state

Crane publishes release candidates rather than finals, and the whole of 0.3.2 is carried by a single rc2 body — its two sibling tags are one-line styling commits, one of them tagged with an unsubstituted vX.Y.Z placeholder. The rc2 notes run to dozens of additions across regression tables, line plots and hierarchical rate tables.

◆ Where it's heading

The package is moving from plotting helpers to a full analysis-output layer: mixed models for repeated measures, pairwise Cox results, risk-management-plan tables and adverse-event incidence rates all arrive in one cycle, and the annotation machinery underneath was rebuilt for reliable table-to-axis alignment. Defaults are being pulled toward SAS and rtables output — the log-rank test now uses survival::survdiff instead of coin, and survfit confidence intervals default to plain rather than log.

◆ Prediction

Expect a 0.3.2 final close behind rc2, and the deprecated g_lineplot() family to be removed once gg_lineplot() and annotate_gg() have settled.

An actuarial mainstay spends its releases on CI plumbing, not on new mathematics.

◆ Current state

lifecontingencies is a long-running R package for actuarial life-contingency mathematics. Its three most recent tags show a maintainer keeping the infrastructure alive rather than extending the library: 1.5.2 is entirely author-metadata corrections, CI workflow repairs and release automation, 1.4.4 moved presentValue() onto Rcpp, and 1.4.1 states outright that it is identical to the version before it. The 1.5.2 notes jump from 1.4.4, so whatever happened in between never reached this feed.

◆ Where it's heading

The one genuine engineering thread is performance: rewriting presentValue() in Rcpp targets the innermost loop of every annuity and insurance valuation the package performs. Everything since has been about keeping CRAN checks green across platforms — TinyTeX install order, cross-platform caching, automated release tagging — plus a set of Italian actuarial benchmark tests that pin results against published tables. That is maintenance discipline on a stable API, not expansion.

◆ Prediction

Expect further patch tags carrying CI and documentation work, with any Rcpp performance work extending from presentValue() into adjacent valuation functions if it continues at all.
