miscmetabar vs skylight: at a glance
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.
What is skylight?
A frozen astronomical model quietly became the inner loop of its sibling's optimizer.
skylight returns sun and moon illuminance, azimuth and altitude for a given date, time and location, implemented as a near-verbatim transcription of a 1987 US Naval Observatory circular. The model formulation has not changed since the initial 2022 release and the author states so explicitly. Everything shipped since has been packaging, citation and speed: v1.3 moved the main routine from R to C++, and v1.4 removed a parameter check that was flooding the console with messages.

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.

A frozen astronomical model quietly became the inner loop of its sibling's optimizer.
◆ Current state
skylight returns sun and moon illuminance, azimuth and altitude for a given date, time and location, implemented as a near-verbatim transcription of a 1987 US Naval Observatory circular. The model formulation has not changed since the initial 2022 release and the author states so explicitly. Everything shipped since has been packaging, citation and speed: v1.3 moved the main routine from R to C++, and v1.4 removed a parameter check that was flooding the console with messages.
◆ Where it's heading
This is a reference implementation of a published algorithm rather than a product accumulating features, and it is being maintained that way. The movement that does occur is driven from downstream: the C++ port was written for the inverse-modelling loop in the sibling skytrackr package, which calls skylight repeatedly during optimization. That reframes skylight from a standalone calculator into the compute kernel another package's fitting routine depends on.
◆ Prediction
With the model formulation deliberately fixed and the C++ path already in place, the next release is most likely another small maintenance fix. The entries give no indication of planned new capability.
