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 surveycore?

surveycore declared its API stable with every survey design type covered.

surveycore is the estimation engine of a two-package survey stack, handling design objects and variance estimation while surveytidy supplies the dplyr verbs on top. The June release marks it 1.0.0 and states the API is complete and stable across Taylor series linearization, replicate weights, two-phase and non-probability designs, with means, totals, frequencies, quantiles, ratios, correlations, regression, t-tests, ANOVA and effective sample size all in place.

pr2database vs surveycore: editorial side-by-side

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.

surveycore declared its API stable with every survey design type covered.

◆ Current state

surveycore is the estimation engine of a two-package survey stack, handling design objects and variance estimation while surveytidy supplies the dplyr verbs on top. The June release marks it 1.0.0 and states the API is complete and stable across Taylor series linearization, replicate weights, two-phase and non-probability designs, with means, totals, frequencies, quantiles, ratios, correlations, regression, t-tests, ANOVA and effective sample size all in place.

◆ Where it's heading

The last months before 1.0.0 were spent making the awkward designs behave like the ordinary ones. Non-probability designs gained jackknife replicate schemes and got their bootstrap repweights routed through the replicate-weight variance estimator in survey_glm(), matching every other estimation function. The survey_collection abstraction — several surveys treated as one pseudo-data-frame — was tightened rather than extended: divergent grouping across members now errors instead of stitching a patchwork with bind_rows(), and the missing-variable argument was renamed and given a stored default on the collection itself. A documentation audit before 1.0.0 turned up six dispatch and print bugs and corrections across forty-plus files, which is the kind of thing that surfaces when an API is being frozen rather than extended.

◆ Prediction

A declared-stable API means the next releases should be additive or corrective rather than breaking, and the pre-1.0.0 pattern of breaking renames should stop. The tight version pinning between the two packages means surveytidy releases will keep following surveycore's.
