cbcTools vs onemap
A side-by-side editorial comparison of cbcTools and onemap — release velocity, themes, recent moves, and the top alternatives to consider.
cbcTools vs onemap: at a glance
What is cbcTools?
Two years quiet, then a release that makes its greedy design methods practical
cbcTools generates and evaluates designs for choice-based conjoint experiments, gathering several strategies behind one method argument in cbc_design(): random, orthogonal via DoE.base, D-optimal, Bayesian D-efficient and greedy. That structure was set during 2023 across 0.4.0 and 0.5.0, which introduced the method argument, added strategies and documented in a table which options each one supports. The only release since, in August 2025, removes efficiency limitations from the greedy methods.
What is onemap?
A genetic-mapping mainstay that now points new users toward MAPpoly at load time
OneMap constructs genetic linkage maps for experimental crosses, and its 3.x line turned it into a hub in a wider mapping toolchain: export functions for VIEWpoly and QTLpoly, summary and interactive ordering functions adapted from MAPpoly, and retention of reference and alternative allele information from imported VCFs. The most recent release, 3.2.0 in January 2025, adds an announcement about MAPpoly to the README and the package load message, fixes a subscript-out-of-bounds warning in rf_2pts and refreshes vignettes and tests.

◆ Current state
cbcTools generates and evaluates designs for choice-based conjoint experiments, gathering several strategies behind one method argument in cbc_design(): random, orthogonal via DoE.base, D-optimal, Bayesian D-efficient and greedy. That structure was set during 2023 across 0.4.0 and 0.5.0, which introduced the method argument, added strategies and documented in a table which options each one supports. The only release since, in August 2025, removes efficiency limitations from the greedy methods.
◆ Where it's heading
The package was explicitly built for extension — the 0.4.0 notes say the function is now better set up to add methods in future — and the pattern since has been adding or repairing one method at a time behind a stable interface. After a two-year gap the recent work is performance rather than coverage, which suggests the greedy methods were slow enough to be impractical at realistic design sizes. Restrictions have been added deliberately too, such as blocking the label argument for orthogonal designs because it would destroy orthogonality.
◆ Prediction
On the extension pattern the maintainer set up, the next release most likely adds another design method or continues tuning existing ones for speed; the entries do not indicate which.

◆ Where it's heading
Versions 3.0.0 and 3.1.0 were driven by a benchmarking preprint on genotyping-by-sequencing best practice, and their content follows directly: marker filtering from two-point estimates, memory reduction after filtering, and optimisation of find_bins and map_avoid_unlinked. What has happened since is signposting rather than capability — a package that spent two releases integrating with MAPpoly now tells users about it every time it loads. The pre-3.0 tags are backfilled, with versions 2.3 through 2.7 sharing a single August 2021 timestamp, so their order carries no information.
◆ Prediction
The load-message announcement suggests attention is flowing toward the MAPpoly side of the toolchain; expect maintenance and compatibility releases here rather than new mapping algorithms.

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