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 vcmeta?

A meta-analysis toolkit still renaming its own API as it adds effect sizes.

vcmeta provides confidence-interval methods for meta-analysis across correlations, proportions, odds ratios, standardized mean differences and reliability, plus replication-study counterparts to most of them. Each release both widens the function inventory and reshuffles it. The most recent one adds agreement and generalised log-average functions while deleting one function and renaming six others.

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.

A meta-analysis toolkit still renaming its own API as it adds effect sizes.

◆ Current state

vcmeta provides confidence-interval methods for meta-analysis across correlations, proportions, odds ratios, standardized mean differences and reliability, plus replication-study counterparts to most of them. Each release both widens the function inventory and reshuffles it. The most recent one adds agreement and generalised log-average functions while deleting one function and renaming six others.

◆ Where it's heading

The package is converging on a naming scheme, with odds becoming oddsratio and ratio.prop2 becoming propratio2, and it is willing to break calling code to get there. Two of the last three releases carry a self-declared breaking parameter change, both cases where an assumption that used to be baked in became something the user must supply. Growth in the function set is steady rather than directional.

◆ Prediction

Expect the renaming pass to continue into the remaining inconsistent names, alongside more replication-study counterparts to existing estimators.
