compositional.mle vs patRoon
A side-by-side editorial comparison of compositional.mle and patRoon — release velocity, themes, recent moves, and the top alternatives to consider.

compositional.mle vs patRoon: at a glance
What is compositional.mle?
An MLE package rebuilt around composable solvers, then renamed to match.
compositional.mle performs numerical maximum likelihood estimation in R, with the optimisation strategy expressed as composed pieces rather than configured up front. It began in November 2025 as numerical.mle, a configuration-object package with fixed solvers. The v0.2.0 rewrite replaced that with solver factories sharing a uniform signature and operators for chaining and racing them, and renamed the package accordingly. The two most recent releases are CRAN submission work.
What is patRoon?
patRoon 3.0.0 adds ion mobility, opening a dimension its workflows never had.
patRoon is an R workflow platform for non-target mass spectrometry screening, orchestrating feature detection, grouping, annotation and identification across many external tools. Version 3.0.0 is a major release adding support for ion mobility separation, new feature detection and grouping algorithms, revised identification confidence estimation, and use of sample metadata. The preceding five releases were maintenance, with the last comparable step being MS2Tox and MS2Quant integration in 2.3.0.

◆ Current state
compositional.mle performs numerical maximum likelihood estimation in R, with the optimisation strategy expressed as composed pieces rather than configured up front. It began in November 2025 as numerical.mle, a configuration-object package with fixed solvers. The v0.2.0 rewrite replaced that with solver factories sharing a uniform signature and operators for chaining and racing them, and renamed the package accordingly. The two most recent releases are CRAN submission work.
◆ Where it's heading
The arc is a design idea overtaking an implementation: version 0.1.0 exposed configuration functions and named solvers, version 0.2.0 turned solvers into values that can be sequenced with %>>%, raced with %|%, restarted, or conditionally refined, and separated the statistical problem from the optimisation strategy. Since then all effort has gone into CRAN acceptance, dead code removal, policy compliance, validation fixes. That is a package that redesigned itself early and is now trying to get through the door.
◆ Prediction
With the composable API settled, the next work will most likely be additional solvers and transformers plugged into the existing operators rather than another redesign.

patRoon 3.0.0 adds ion mobility, opening a dimension its workflows never had.
◆ Current state
patRoon is an R workflow platform for non-target mass spectrometry screening, orchestrating feature detection, grouping, annotation and identification across many external tools. Version 3.0.0 is a major release adding support for ion mobility separation, new feature detection and grouping algorithms, revised identification confidence estimation, and use of sample metadata. The preceding five releases were maintenance, with the last comparable step being MS2Tox and MS2Quant integration in 2.3.0.
◆ Where it's heading
The pattern is long maintenance stretches punctuated by releases that add a whole capability: toxicity and concentration prediction at 2.3.0, then ion mobility at 3.0.0. Feed entries are short pointers to the NEWS file rather than full changelogs, so the fine detail of each release sits outside this feed, but the headline claims are specific enough to read direction from. The upgrade notes flagged in the 3.0.0 summary indicate this one is not a drop-in replacement.
◆ Prediction
Expect the next releases to be maintenance work stabilising the ion mobility path, following the same rhythm that followed 2.3.0.
