lifecontingencies vs rapr: at a glance
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.
What is rapr?
rapr generalises its Rangeland Analysis Platform API access one endpoint at a time
rapr pulls Rangeland Analysis Platform data into R — vegetation cover and production rasters derived from Landsat and Sentinel-2, plus the tabular summary APIs. The 1.1.3 release replaces the single-purpose table function with a general get_rap_table() covering the cover, coverMeteorology, production and production16day endpoints. The package reached CRAN in 2025 and is maintained by brownag, who also maintains the GeoPackage interface gpkg.

◆ 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.

rapr generalises its Rangeland Analysis Platform API access one endpoint at a time
◆ Current state
rapr pulls Rangeland Analysis Platform data into R — vegetation cover and production rasters derived from Landsat and Sentinel-2, plus the tabular summary APIs. The 1.1.3 release replaces the single-purpose table function with a general get_rap_table() covering the cover, coverMeteorology, production and production16day endpoints. The package reached CRAN in 2025 and is maintained by brownag, who also maintains the GeoPackage interface gpkg.
◆ Where it's heading
The shape is familiar for a young API client: add access to one endpoint, then generalise it once a second endpoint proves the pattern. get_rap_production16day_table() arrived in 1.1.0 and was deprecated three releases later in favour of a product argument. Between those, the work was error handling — empty geometries, server-side HTTP failures, warning timing — the unglamorous half of wrapping a remote service. The 1.0.0 release had already set the ambition by exposing both the 30m Landsat and 10m Sentinel-2 sources behind one argument.
◆ Prediction
Expect the remaining RAP endpoints to be folded into get_rap_table() as they are needed, and the deprecated 16-day function to be removed once the general interface has been out long enough.
