fastml vs miscmetabar: at a glance
What is fastml?
fastml added survival modelling and leakage-proof resampling, moving past classification and regression.
A tidymodels-based AutoML wrapper that trains, tunes and compares many engines from one call. The 0.6.x line added engine-specific tuning parameters, class-imbalance handling, early stopping and DALEX-based explainability. The 0.7.5 release is far larger: a full survival analysis task with its own engines, MICE imputation and integrated Brier scoring, plus unbiased nested cross-validation, grouped, blocked and rolling resampling helpers, fold-wise imputation, recipe leakage checks, and a sandbox for user-supplied preprocessing.
What is miscmetabar?
A phyloseq toolbox keeps absorbing metabarcoding methods, and has started splitting into a family.
MiscMetabar extends the phyloseq ecosystem for metabarcoding analysis — taxonomic assignment, diversity curves, filtering and plotting for amplicon sequencing data. Recent substantive releases added IDTAXA-based assignment via DECIPHER, UMAP dimensionality reduction, Hill diversity accumulation curves and kmer complexity plots. The most recent release is a CRAN submission bundling several development merges, including a fix for ggplot2 v4.0.0 breaking the upset plot.

◆ Current state
A tidymodels-based AutoML wrapper that trains, tunes and compares many engines from one call. The 0.6.x line added engine-specific tuning parameters, class-imbalance handling, early stopping and DALEX-based explainability. The 0.7.5 release is far larger: a full survival analysis task with its own engines, MICE imputation and integrated Brier scoring, plus unbiased nested cross-validation, grouped, blocked and rolling resampling helpers, fold-wise imputation, recipe leakage checks, and a sandbox for user-supplied preprocessing.
◆ Where it's heading
The package is moving from convenience wrapper to something that has to be defensible statistically. Nested cross-validation, fold-wise rather than up-front imputation, and explicit leakage checks are all corrections to the shortcuts that make AutoML easy and its scores optimistic. Survival adds a third task type alongside classification and regression, and it arrived with its own metrics rather than being bolted onto the existing ones. Note the entry body is cut off at 8,000 characters, so the release is larger than what is shown.
◆ Prediction
Expect the remaining survival engines to fill in and the sandboxing of custom preprocessing to tighten, since both were still being iterated on within this same release's commit list.
miscmetabar
0.0ANALYTICS
A phyloseq toolbox keeps absorbing metabarcoding methods, and has started splitting into a family.
◆ Current state
MiscMetabar extends the phyloseq ecosystem for metabarcoding analysis — taxonomic assignment, diversity curves, filtering and plotting for amplicon sequencing data. Recent substantive releases added IDTAXA-based assignment via DECIPHER, UMAP dimensionality reduction, Hill diversity accumulation curves and kmer complexity plots. The most recent release is a CRAN submission bundling several development merges, including a fix for ggplot2 v4.0.0 breaking the upset plot.
◆ Where it's heading
The package grows by adopting established methods from elsewhere in the bioinformatics stack rather than inventing its own, wrapping them for phyloseq objects. The 0.11.0 notes floated a pq-verse — splitting functionality into companion packages such as comparpq for comparing phyloseq objects with different taxonomies, explicitly to make maintenance easier. Several releases in this window carry no notes beyond a merge commit, so the feed understates the work behind them.
◆ Prediction
The pq-verse split was described as an intention rather than delivered here, so companion packages appearing alongside a slimmer core is the most likely next structural move. Continued ggplot2 v4 compatibility work is the near-term certainty.
