What is pr2database?

The protist reference database keeps widening past the rRNA gene it was built on.

PR2 curates ribosomal reference sequences for eukaryotes, distributed as flat files and through a web interface, with each release crediting the specialists who curated individual clades. Since 2022 the structural changes have outweighed the curation: one combined SSU database replaced the separate ones, the taxonomy moved from eight levels to nine, and companion databases for ribosomal operons, mixoplankton and mitochondrial COI have been linked in.

What is usmapdata?

usmapdata ships its 2025 shapefiles on the year-indexed model it adopted in 0.4.0.

usmapdata supplies the boundary data behind usmap's plotting functions. Since 0.4.0 it has been year-indexed: us_map(data_year = ) selects a vintage, and each Census release is added as its own year with older ones still reachable. 1.1.0 adds 2025. 1.0.0 closed the package's longest-standing gap by adding Puerto Rico, retroactively across every vintage.

0.0

The protist reference database keeps widening past the rRNA gene it was built on.

◆ Current state

PR2 curates ribosomal reference sequences for eukaryotes, distributed as flat files and through a web interface, with each release crediting the specialists who curated individual clades. Since 2022 the structural changes have outweighed the curation: one combined SSU database replaced the separate ones, the taxonomy moved from eight levels to nine, and companion databases for ribosomal operons, mixoplankton and mitochondrial COI have been linked in.

◆ Where it's heading

The database is becoming a hub rather than a single file. Each recent release integrates something maintained elsewhere, with the ROD, EukRibo, Mixoplankton and now eKOI databases reachable through the same interface, while the SSU flat files themselves change little between versions. Curation continues underneath, clade by clade, at a pace set by which specialist contributed that cycle.

◆ Prediction

Expect the next release to integrate or refresh another linked database while the SSU files see routine curation, following the pattern of the last three.

2.5

usmapdata ships its 2025 shapefiles on the year-indexed model it adopted in 0.4.0.

◆ Current state

usmapdata supplies the boundary data behind usmap's plotting functions. Since 0.4.0 it has been year-indexed: us_map(data_year = ) selects a vintage, and each Census release is added as its own year with older ones still reachable. 1.1.0 adds 2025. 1.0.0 closed the package's longest-standing gap by adding Puerto Rico, retroactively across every vintage.

◆ Where it's heading

The package has settled into a predictable rhythm — one shapefile vintage per year, with structural change rare and clustered. The two changes that mattered were data_year in 0.4.0, which turned a single-vintage dataset into a time series, and the tibble-to-data-frame switch in 0.6.0 that reduced what downstream callers have to depend on.

◆ Prediction

The stated policy — each year added going forward, previous years reachable through data_year — points to a 2026 vintage as the next release. Nothing in these notes suggests further change to the data model.
