parafac4microbiome vs volcalc: at a glance
What is parafac4microbiome?
A PARAFAC toolkit for microbiome time series, spending every release on packaging
parafac4microbiome fits parallel factor analysis models to longitudinal microbiome data, built on the Bioconductor data structures that field uses. All three releases in its recorded history concern the packaging boundary rather than the modelling: an R 4.5 compatibility release that pinned minimum versions of TreeSummarizedExperiment, MicrobiotaProcess and SummarizedExperiment, a README URL fix, and the removal of importMicrobiotaProcess for not meeting CRAN requirements.
What is volcalc?
Rebuilt itself around SMILES and .mol input, then made the chemistry configurable
volcalc estimates the volatility of chemical compounds from their structure, implementing the SIMPOL.1 group-contribution method and the Meredith et al. variant. Version 2.0.0 severed the package from KEGG: calc_vol() takes .mol file paths or SMILES strings directly, is vectorized over multiple compounds, and the group-contribution maths was split into its own simpol1() function. Work since has been chemistry accuracy and configurability — the full set of SIMPOL.1 functional groups, volatility thresholds for clean atmosphere, polluted atmosphere or soil, user-supplied temperature, and a validate option returning NA when structure parsing looks suspect.

◆ Current state
parafac4microbiome fits parallel factor analysis models to longitudinal microbiome data, built on the Bioconductor data structures that field uses. All three releases in its recorded history concern the packaging boundary rather than the modelling: an R 4.5 compatibility release that pinned minimum versions of TreeSummarizedExperiment, MicrobiotaProcess and SummarizedExperiment, a README URL fix, and the removal of importMicrobiotaProcess for not meeting CRAN requirements.
◆ Where it's heading
The visible arc is a CRAN package caught between two ecosystems: its scientific dependencies live on Bioconductor and move on Bioconductor's schedule, while its distribution channel enforces CRAN's rules. Both consequences are already on the record — compatibility with older Ubuntu was broken when versions had to be pinned, and a data import path was lost outright. Nothing in these entries describes a change to the PARAFAC modelling itself.
◆ Prediction
Expect further releases driven by Bioconductor dependency changes rather than by the method; whether the removed MicrobiotaProcess import returns depends on a packaging problem the notes do not describe.

◆ Current state
volcalc estimates the volatility of chemical compounds from their structure, implementing the SIMPOL.1 group-contribution method and the Meredith et al. variant.

Work since has been chemistry accuracy and configurability — the full set of SIMPOL.1 functional groups, volatility thresholds for clean atmosphere, polluted atmosphere or soil, user-supplied temperature, and a validate option returning NA when structure parsing looks suspect.
◆ Where it's heading
The arc runs from a script tied to one database toward a general structure-to-volatility tool. Dropping KEGG from the core in 2.0.0, then removing KEGGREST as a dependency entirely in 2.2.0, took the package from volatility for KEGG compounds to volatility for any structure a user can supply. The accompanying manuscript published in 2023, and the changelog since has been careful about coefficient double-counting — amines and amides have each been corrected — which suggests the group definitions are the part under active scrutiny.
◆ Prediction
The smarts_simpol1 dataset added in 2.2.0 documents how functional groups are defined, pointing toward further estimation methods alongside SIMPOL.1 and Meredith; splitting simpol1() out in 2.0.0 was stated to be groundwork for exactly that.
