ethiodate vs onemap
A side-by-side editorial comparison of ethiodate and onemap — release velocity, themes, recent moves, and the top alternatives to consider.
ethiodate vs onemap: at a glance
What is ethiodate?
The Ethiopian calendar becomes a first-class R date class, ggplot2 axes included.
ethiodate implements the Ethiopian calendar as an R date class. Over three releases it has gone from conversion helpers to something that behaves like a date type: ggplot2 scales and breaks, quarter extraction, and seq() and cut() methods defined for the ethdate class. The most recent release is a robustness fix for summary.ethdate() under R 4.6.0 and later.
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
ethiodate implements the Ethiopian calendar as an R date class. Over three releases it has gone from conversion helpers to something that behaves like a date type: ggplot2 scales and breaks, quarter extraction, and seq() and cut() methods defined for the ethdate class. The most recent release is a robustness fix for summary.ethdate() under R 4.6.0 and later.
◆ Where it's heading
The work follows the standard path for a custom date class in R: get the arithmetic right, then implement the generics the rest of the ecosystem calls, then handle vector recycling and precision. Switching internal storage from integer to double in 0.3.0 is a quiet but load-bearing change, and accepting numeric months widens the input surface. Each release closes another gap between ethdate and Date.
◆ Prediction
Expect the remaining base generics and formatting paths to be filled in, and continued fixes tracking R's own changes. The package is close enough to full coverage that the next releases will mostly be about edge cases.

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