fracture vs robma
A side-by-side editorial comparison of fracture and robma — release velocity, themes, recent moves, and the top alternatives to consider.
fracture vs robma: at a glance
What is fracture?
fracture solved decimal-to-fraction conversion years ago and now only answers to CRAN.
A single-purpose package converting decimals to fractions, with a matrix form and a Unicode pretty-printer. The functional work finished in 2021-2022: an explicit denom argument, named-argument-only calling, sensible denominators at 0 and 1, and NA and Inf handled rather than erroring. The only release since is a four-year-later removal of a C++11 system requirement that R's C++17 default made redundant.
What is robma?
RoBMA 4.0 tears out its own constructor surface and rebuilds on one class hierarchy
RoBMA fits robust Bayesian model-averaged meta-analyses that adjust for publication bias. The 3.x line grew by accretion: separate constructors for each model family (RoBMA.reg, NoBMA, BiBMA and their .reg variants), a spike-and-slab algorithm in 3.3.0 that made estimation fast enough to matter, then a steady stream of post-estimation tooling gated on that algorithm — heterogeneity summaries, residuals, funnel plots, z-curve conversion, predict, extract, pooled and adjusted effects. Version 4.0.0 in May 2026 collapses all of it into a unified brma class hierarchy.

◆ Current state
A single-purpose package converting decimals to fractions, with a matrix form and a Unicode pretty-printer. The functional work finished in 2021-2022: an explicit denom argument, named-argument-only calling, sensible denominators at 0 and 1, and NA and Inf handled rather than erroring. The only release since is a four-year-later removal of a C++11 system requirement that R's C++17 default made redundant.
◆ Where it's heading
This is a completed utility. Its arc ran from correctness — floating-point rounding, exhaustive tests across millions of fractions — through API tightening, to edge-case tolerance, and then stopped. The 2026 release contains no user-visible change at all; it exists because CRAN's toolchain moved, which is the characteristic maintenance mode of a small package that does one thing correctly.
◆ Prediction
Nothing in these entries suggests new functionality; expect further releases only when R or CRAN policy forces one, as this one did.

RoBMA 4.0 tears out its own constructor surface and rebuilds on one class hierarchy
◆ Current state
RoBMA fits robust Bayesian model-averaged meta-analyses that adjust for publication bias. The 3.x line grew by accretion: separate constructors for each model family (RoBMA.reg, NoBMA, BiBMA and their .reg variants), a spike-and-slab algorithm in 3.3.0 that made estimation fast enough to matter, then a steady stream of post-estimation tooling gated on that algorithm — heterogeneity summaries, residuals, funnel plots, z-curve conversion, predict, extract, pooled and adjusted effects. Version 4.0.0 in May 2026 collapses all of it into a unified brma class hierarchy.
◆ Where it's heading
The 3.x series solved the modeling problem and left an interface problem behind: a caller had to know which of six constructors matched their data type, and argument names differed across them. 4.0.0 resolves that by making the model family a set of arguments rather than a function name, and by standardizing input naming on metafor-style conventions. It shipped one day after BayesTools 0.3.0, the author's own upstream infrastructure package, whose new standardization and prior-transformation machinery this rewrite depends on.
◆ Prediction
A rewrite this wide usually needs a follow-up, so expect 4.0.x patches addressing migration gaps as users hit the removed constructors and renamed arguments.

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