The recursive-computation engine under massProps grows the accessors its consumer needed
A side-by-side editorial comparison of selection.index and traumar — release velocity, themes, recent moves, and the top alternatives to consider.
A dormant plant-breeding package returns as a genomic selection index suite
selection.index computes selection indices for plant breeding — weighting several traits into one number breeders can rank on. After two years of silence it shipped 2.0.0 in March 2026, and the package is barely recognisable: snake_case throughout, an Rcpp and RcppEigen computational core, and index families for genomic data, marker data, multi-stage trials and constrained genetic gain sitting beside the original phenotypic ones.
Trauma registry statistics in R, tightening the numbers it reports against the literature.
traumar computes trauma-centre performance measures from registry data, including relative mortality metrics, SEQIC quality indicators and predicted survival probability. The recent releases are dominated by correctness rather than coverage: 1.2.5 changed how the denominator for SEQIC indicator 7 is derived so it reflects the definitive care population rather than a raw row count, and 1.2.3 realigned probability_of_survival() with published coefficients. Version 1.2.6 completes a deprecation, turning the old n_decimal argument into an error.

The first version series added one function at a time — combinatorial indices, then genetic advance, then mean performance under randomised block designs — against a fixed phenotypic framing. Version 2.0.0 abandons that framing rather than extending it. Genomic and marker information become inputs the package understands, multi-cycle simulation becomes a built-in toolset, and the old combinatorial entry points are replaced by a named lpsi(). The 2.0.1 follow-up is entirely CI and numerical-stability work, which reads like a maintainer bracing a much larger surface.
A seventeen-runner CI matrix mirroring every CRAN check flavour, added days after 2.0.0, says the immediate concern is keeping a compiled multi-family package green rather than adding to it. Expect stabilisation releases before anything new.
traumar computes trauma-centre performance measures from registry data, including relative mortality metrics, SEQIC quality indicators and predicted survival probability. The recent releases are dominated by correctness rather than coverage: 1.2.5 changed how the denominator for SEQIC indicator 7 is derived so it reflects the definitive care population rather than a raw row count, and 1.2.3 realigned probability_of_survival() with published coefficients. Version 1.2.6 completes a deprecation, turning the old n_decimal argument into an error.
This is a package whose outputs are reported numbers, and it is behaving accordingly: the notable changes in this window alter results rather than add features. A denominator computed as a row count instead of a filtered population, and a survival calculation not matching the coefficients it cites, are both the kind of defect that quietly propagates into published figures, and both were corrected here. Around that sit in-house validation helpers written deliberately to avoid a new dependency, and a steady tidy-up of tests and tooling.
Expect the validation family introduced in 1.2.4 to be applied more widely across the package's entry points, now that it exists and is deliberately kept internal. Further SEQIC indicators being reviewed against their definitions looks likely given indicator 7 needed it, though the entries name no specific one as next.

Latest ship moves from both products, interleaved chronologically. ⚡ = editorial spark.
They serve adjacent needs but don't currently overlap on shipped themes. selection.index and traumar are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. selection.index and traumar are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
