What is emuR?

The R half of the EMU speech database system, fixing what was quietly broken.

emuR is the R interface to the EMU Speech Database Management System — loading annotated speech corpora, running hierarchical queries over annotation levels, extracting signal track data, and serving corpora to the EMU-webApp for browser-based annotation. It is at 2.6.0 on a slow cadence of roughly one release a year. Recent work has centred on the CRUD operations for annotation items and on widening what serve() can hand the web application.

What is selection.index?

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.

The R half of the EMU speech database system, fixing what was quietly broken.

◆ Current state

emuR is the R interface to the EMU Speech Database Management System — loading annotated speech corpora, running hierarchical queries over annotation levels, extracting signal track data, and serving corpora to the EMU-webApp for browser-based annotation. It is at 2.6.0 on a slow cadence of roughly one release a year. Recent work has centred on the CRUD operations for annotation items and on widening what serve() can hand the web application.

◆ Where it's heading

The releases read as a package being brought up to the standard its own API implied. delete_itemsInLevel() shipped in 2.1.1 as a first version, was described in 2.5.0 as heavily flawed and now usable, and the create/update/delete family is still called ongoing work. Alongside that, the query engine was rewritten onto CTEs and the signal-processing layer is being opened past the bundled wrassp, starting with Matlab. Speed work recurs — SQLite transactions, prepared statements, on-the-fly caching — consistent with corpora outgrowing the original design.

◆ Prediction

Two threads are explicitly unfinished: the CRUD documentation and behaviour, described as ongoing, and the add_signalVia family, described as a draft starting with Matlab. Expect the next release to advance one of them rather than open new ground.

A dormant plant-breeding package returns as a genomic selection index suite

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

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.

Frequently asked questions

What is the difference between emuR and selection.index?

They serve adjacent needs but don't currently overlap on shipped themes. emuR and selection.index 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.

Is emuR better than selection.index?

Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. emuR and selection.index are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
