selection.index vs trackeR
A side-by-side editorial comparison of selection.index and trackeR — release velocity, themes, recent moves, and the top alternatives to consider.
selection.index vs trackeR: at a glance
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.
What is trackeR?
Fitness-tracking analysis in slow maintenance, still absorbing upstream breakage.
trackeR reads GPS and fitness-tracker files in TCX, GPX and JSON form and turns them into session data, distribution and concentration profiles, and route plots. Feature work concentrated in the 1.5 series in 2019; the two releases since are corrective. The latest swaps the plot layout dependencies for patchwork and fixes plot_route() returning nothing.

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.
trackeR
0.0INFRA · APIS
Fitness-tracking analysis in slow maintenance, still absorbing upstream breakage.
◆ Current state
trackeR reads GPS and fitness-tracker files in TCX, GPX and JSON form and turns them into session data, distribution and concentration profiles, and route plots. Feature work concentrated in the 1.5 series in 2019; the two releases since are corrective. The latest swaps the plot layout dependencies for patchwork and fixes plot_route() returning nothing.
◆ Where it's heading
Recent releases track other people's changes: ggmap moving to Stadia maps, gridExtra giving way to patchwork, a cadence field being read into the wrong column. The 2019 entries are where the analysis surface was built out, with cumulative elevation gain, compressed file reading and elevation-noise thresholds, and it has not moved much since.
◆ Prediction
Expect the next release to be another compatibility or parsing fix rather than a new metric.

Frequently asked questions
What is the difference between selection.index and trackeR?
They serve adjacent needs but don't currently overlap on shipped themes. selection.index and trackeR 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 selection.index better than trackeR?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. selection.index and trackeR are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
