cofad vs onemap
A side-by-side editorial comparison of cofad and onemap — release velocity, themes, recent moves, and the top alternatives to consider.
cofad vs onemap: at a glance
What is cofad?
Contrast analysis with a Shiny front end, shipping about one release a year
cofad performs contrast analyses for factorial designs in both between- and within-subject forms, and ships a Shiny GUI alongside the R interface. The 0.3.0 release in 2024 was the substantial one: a helper for calculating differences between two sets of lambdas for competing contrast analysis, improved summary output, removal of the plyr dependency, a rebuilt Shiny interface using standard elements after the sortable drag-and-drop proved unstable, and a change of maintainer to Johannes Titz. The most recent release is a one-line patch fixing degrees of freedom in the t-test table.
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
cofad performs contrast analyses for factorial designs in both between- and within-subject forms, and ships a Shiny GUI alongside the R interface. The 0.3.0 release in 2024 was the substantial one: a helper for calculating differences between two sets of lambdas for competing contrast analysis, improved summary output, removal of the plyr dependency, a rebuilt Shiny interface using standard elements after the sortable drag-and-drop proved unstable, and a change of maintainer to Johannes Titz. The most recent release is a one-line patch fixing degrees of freedom in the t-test table.
◆ Where it's heading
Development is slow and correctness-led. The record runs from a JOSS publication in 2021 through a near three-year gap to a release that both extended the method and repaired the GUI, then a degrees-of-freedom fix. Maintainer and author order changed in 0.3.0, which typically marks a handover rather than a burst of new work, and the cadence since is consistent with that.
◆ Prediction
Expect low-frequency correctness releases; the competing contrast analysis helper added in 0.3.0 is the most likely thing to be extended if anything is.

A genetic-mapping mainstay that now points new users toward MAPpoly at load time
◆ 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.

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