onemap vs xpose4
A side-by-side editorial comparison of onemap and xpose4 — release velocity, themes, recent moves, and the top alternatives to consider.
onemap vs xpose4: 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 xpose4?
NONMEM's veteran diagnostics package, now moving at about one fix a year
xpose4 generates diagnostic plots for nonlinear mixed-effect models fitted in NONMEM, a role it has held since 2014 when five packages were consolidated into one. The three most recent releases are a documentation cross-reference update, a change of the default table-reading method to the slower and more reliable one, and a set of file-parsing bug fixes. No new plot types appear anywhere in the window.

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.

NONMEM's veteran diagnostics package, now moving at about one fix a year
◆ Current state
xpose4 generates diagnostic plots for nonlinear mixed-effect models fitted in NONMEM, a role it has held since 2014 when five packages were consolidated into one. The three most recent releases are a documentation cross-reference update, a change of the default table-reading method to the slower and more reliable one, and a set of file-parsing bug fixes. No new plot types appear anywhere in the window.
◆ Where it's heading
Development now responds to the R ecosystem rather than to pharmacometrics: deprecated dplyr and tibble calls, readr and gam changes, and R documentation standards account for most recent entries. The last release with visible new capability is 4.6.0 in 2017, which extended xpose.VPC() with outlier identification, median-positioned lines and bin rugs. The feed's older tags are also unreliable — versions 4.5.0 through 4.5.3 all carry the same 2014 timestamp, so their order says nothing about sequence.
◆ Prediction
Expect continued compatibility maintenance at roughly one release a year, triggered by changes in R or in the packages it reads tables with; nothing in these entries points to new diagnostic capability being planned.

Frequently asked questions
What is the difference between onemap and xpose4?
They serve adjacent needs but don't currently overlap on shipped themes. onemap and xpose4 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 xpose4?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. onemap and xpose4 are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
