onemap vs RSA
A side-by-side editorial comparison of onemap and RSA — release velocity, themes, recent moves, and the top alternatives to consider.
onemap vs RSA: at a glance
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.
What is RSA?
Four years quiet, then two releases ninety seconds apart, both about drawing better plots
RSA implements response surface analysis for congruence questions in psychology, built on lavaan. After four and a half years of silence the maintainer pushed 0.10.6 and 0.10.8 within ninety seconds of each other on 2 October 2025, so the feed's version sequence is a backfill of accumulated work rather than two separate release events. Both are plotting releases: user-defined lines and points on the surface, stilts for selected data points, and separate control of point fill and border colour.

◆ Current state
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.
◆ 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.

◆ Current state
RSA implements response surface analysis for congruence questions in psychology, built on lavaan. After four and a half years of silence the maintainer pushed 0.10.6 and 0.10.8 within ninety seconds of each other on 2 October 2025, so the feed's version sequence is a backfill of accumulated work rather than two separate release events. Both are plotting releases: user-defined lines and points on the surface, stilts for selected data points, and separate control of point fill and border colour.
◆ Where it's heading
The statistical core has been stable since 0.10.0 in 2020, which added control variables, pooled centering and a corrected AICc. Everything since is either plot customisation or a reaction to a dependency — lavaan model comparison, rgl deprecations, tkrplot on Apple Silicon, the ggplot2 fill aesthetic. This is a mature method implementation in maintenance, where the visible work is making its surface plots publishable.
◆ Prediction
Further releases are most likely dependency reactions, with rgl and ggplot2 the two that have repeatedly forced changes, and plot customisation arriving in batches whenever the maintainer returns to the package.

Frequently asked questions
What is the difference between onemap and RSA?
They serve adjacent needs but don't currently overlap on shipped themes. onemap and RSA 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 onemap better than RSA?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. onemap and RSA are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). For your specific use case, the alternatives sections above list other Infra & APIs products to evaluate alongside.
