Fiscal vs onemap
A side-by-side editorial comparison of Fiscal and onemap — release velocity, themes, recent moves, and the top alternatives to consider.
Fiscal vs onemap: at a glance
What is Fiscal?
UK income tax calculations reach CRAN, then go quiet behind pointer-only release notes.
Fiscal computes UK income tax. It reached its 1.0.0 milestone in March 2026 and shipped two patch releases in the fortnight after, then stopped. The GitHub release bodies carry no changelog of their own: each one points at the NEWS file and the CRAN page, so the feed shows cadence but not content.
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.

UK income tax calculations reach CRAN, then go quiet behind pointer-only release notes.
◆ Current state
Fiscal computes UK income tax. It reached its 1.0.0 milestone in March 2026 and shipped two patch releases in the fortnight after, then stopped. The GitHub release bodies carry no changelog of their own: each one points at the NEWS file and the CRAN page, so the feed shows cadence but not content.
◆ Where it's heading
Three releases in a fifteen-day window reads as post-publication cleanup rather than a development push, which is the normal shape after a first CRAN acceptance. Because every body is the same boilerplate, direction has to be read from the tags alone, and the tags say only that two patches followed the 1.0.0 line.
◆ Prediction
The most likely next release is an annual one tracking a new UK tax year's rates and thresholds. The release notes as published give no evidence for anything beyond that.

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.
