What is legendry?

A ggplot2 extension quietly turning axes and legends into a place where other plots can live.

legendry extends ggplot2's guide system, letting axes and legends be composed from primitives and keys rather than accepted as given. The most recent release added guides for user-defined keys, upset matrices, arbitrary symbol placement, freeform annotations, and side-plots attached to an axis, plus a run-length-encoded range key and subtitles on custom axes. Between feature releases the package ships small patches, several of them tracking ggplot2's own changes.

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.

A ggplot2 extension quietly turning axes and legends into a place where other plots can live.

◆ Current state

legendry extends ggplot2's guide system, letting axes and legends be composed from primitives and keys rather than accepted as given. The most recent release added guides for user-defined keys, upset matrices, arbitrary symbol placement, freeform annotations, and side-plots attached to an axis, plus a run-length-encoded range key and subtitles on custom axes. Between feature releases the package ships small patches, several of them tracking ggplot2's own changes.

◆ Where it's heading

The direction is toward treating a guide as a rendering slot rather than a label strip. Dendrogram scales arrived in 0.2.0 with a matching axis guide; the newest release adds side-plots and upset symbol matrices to the same position. Each of these puts real graphical content where an axis used to be, and each one ships with a key function so the composition stays user-controllable. Note that this feed's order is unreliable: 0.2.1 was published eight months after 0.2.4 and minutes before 0.3.0, so neither version numbers nor timestamps indicate release order here.

◆ Prediction

The pattern of pairing each new guide with a matching key function is consistent enough that the next feature release will likely follow it again; the recurring forwards-compatibility patches also suggest another ggplot2-tracking release whenever upstream moves.

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.
