A distribution catalogue that grows by one family at a time, and rarely breaks anything.
A side-by-side editorial comparison of miscmetabar and PurpleAir — release velocity, themes, recent moves, and the top alternatives to consider.
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.
The R client for PurpleAir sensors keeps finding its time-averaging was wrong.
PurpleAir is a small R client for the PurpleAir air quality sensor API, covering sensor queries, historical readings, and — more recently — finding a sensor on the local network by IP address and id. Authentication has been simplified to an environment variable only, with the redundant key argument removed. The package is maintained reactively, and most of what ships is correctness work on the queries it already makes.

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.
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.

The recurring theme is time aggregation. Weekly, monthly and yearly average intervals were wrong and fixed in one release; the weekly average was wrong again and fixed in the next. For an air quality package that is not incidental — averaging window is what turns a stream of sensor readings into an exposure estimate, and downstream analyses inherit the error silently. The other thread is failing earlier and more clearly: explicit errors for spatial inputs the sensor query does not accept, better index parsing so malformed requests never reach the API, and handling for history calls that return nothing. Local sensor discovery is the one genuine capability addition, opening a path that does not depend on the cloud API at all.
On this record, further aggregation and input-validation fixes are the likeliest next releases; whether local network access grows past discovery into full local data retrieval is not something the entries indicate.
