dcurves vs MetaboAnalystR: at a glance
What is dcurves?
Decision curve analysis, settled since 2022 and now moving only when its neighbours do
dcurves implements decision curve analysis — evaluating a prediction model or diagnostic test by net benefit across the range of thresholds a clinician might plausibly use, rather than by a single discrimination statistic. Its API stabilised in 2022 around dca() and test_consequences(). The two releases since exist because gtsummary and CRAN documentation rules changed, not because the method did.
What is MetaboAnalystR?
The R engine behind MetaboAnalyst closes the gap from raw spectra to biological interpretation
MetaboAnalystR is the scriptable form of the MetaboAnalyst web platform, carrying several hundred functions for metabolomics data analysis, visualisation and functional interpretation. Its releases have steadily pushed the starting line further upstream: version 1 assumed processed data, version 2 added raw LC-MS spectral processing, and the 4.x line presents the whole path from raw spectra through compound identification to functional interpretation as one workflow. It also now claims exposomics alongside metabolomics as an application area.

Decision curve analysis, settled since 2022 and now moving only when its neighbours do
◆ Current state
dcurves implements decision curve analysis — evaluating a prediction model or diagnostic test by net benefit across the range of thresholds a clinician might plausibly use, rather than by a single discrimination statistic. Its API stabilised in 2022 around dca() and test_consequences(). The two releases since exist because gtsummary and CRAN documentation rules changed, not because the method did.
◆ Where it's heading
The package reached its intended scope quickly and then stopped. Its 2022 releases did the substantive work: adding threshold-level diagnostic accuracy, tightening argument validation, and taking one breaking change to make net-interventions-avoided plots show the treat-all and treat-none reference lines by default. Since then it has moved only as a dependent of the wider tidy-modelling documentation ecosystem it plugs into.
◆ Prediction
Nothing in these entries points to method or API work; expect the next release to be another compatibility or CRAN documentation patch.

The R engine behind MetaboAnalyst closes the gap from raw spectra to biological interpretation
◆ Current state
MetaboAnalystR is the scriptable form of the MetaboAnalyst web platform, carrying several hundred functions for metabolomics data analysis, visualisation and functional interpretation. Its releases have steadily pushed the starting line further upstream: version 1 assumed processed data, version 2 added raw LC-MS spectral processing, and the 4.x line presents the whole path from raw spectra through compound identification to functional interpretation as one workflow. It also now claims exposomics alongside metabolomics as an application area.
◆ Where it's heading
The consistent move is absorbing steps that users previously stitched together from separate tools. Peak picking, alignment and annotation came in with 2.0; automated feature detection optimisation and compound identification came with the 4.x work. The releases are infrequent and paper-shaped — each major version is announced with publication text rather than a change list — which makes the version history read as a sequence of methods papers more than a software cadence.
◆ Prediction
The exposomics framing is the newest element and the least built out in these entries, which makes it the most likely direction for the next round of work.
