MetaboAnalystR vs MultiSpline: at a glance
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.
What is MultiSpline?
MultiSpline went from five functions to a full multilevel spline framework in seven weeks.
MultiSpline fits spline-based nonlinear models to multilevel and longitudinal data in R. The package reached CRAN in February 2026 with five functions covering fitting, summary, prediction, plotting and intraclass correlations. Version 0.2.0, seven weeks later, adds cross-classified and nested random-effect structures, automatic knot selection, a multilevel R-squared variance partition, derivative-based interpretation with turning points, model comparison against polynomials, and cluster heterogeneity analysis, while keeping every 0.1.0 call valid.

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.

0.0ANALYTICS
MultiSpline went from five functions to a full multilevel spline framework in seven weeks.
◆ Current state
MultiSpline fits spline-based nonlinear models to multilevel and longitudinal data in R. The package reached CRAN in February 2026 with five functions covering fitting, summary, prediction, plotting and intraclass correlations. Version 0.2.0, seven weeks later, adds cross-classified and nested random-effect structures, automatic knot selection, a multilevel R-squared variance partition, derivative-based interpretation with turning points, model comparison against polynomials, and cluster heterogeneity analysis, while keeping every 0.1.0 call valid.
◆ Where it's heading
The arc is a research package being built out into a workflow at speed: 0.1.0 could fit a curve, 0.2.0 can tell you where the curve turns, how much variance each level explains, and whether a spline beats a polynomial at all. Backward compatibility was preserved across that expansion, which suggests the author is building for outside users rather than a single paper. The JOSS submission referenced in 0.1.1 points at academic distribution as the intended channel.
◆ Prediction
With the interpretation and diagnostics layers now in place, the next release will most likely extend the supported model families beyond the current lmer and glmer backends.
