pr2database vs valr: at a glance
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 valr?
valr's interval verbs now read genomic files in place instead of demanding a loaded tibble.
valr reimplements bedtools-style genome interval arithmetic as tidyverse verbs backed by C++. Its long project has been closing the behavioural gap with bedtools — the book-ended interval semantics finally match in 0.10.0, three releases after the deprecation began. The July release also ends the assumption that intervals must be in memory: bed_map(), bed_intersect(), bed_subtract(), bed_coverage() and bed_window() accept a bigWig or bigBed path or URL where an interval table used to go.

◆ 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.

0.0INFRA · APIS
valr's interval verbs now read genomic files in place instead of demanding a loaded tibble.
◆ Current state
valr reimplements bedtools-style genome interval arithmetic as tidyverse verbs backed by C++. Its long project has been closing the behavioural gap with bedtools — the book-ended interval semantics finally match in 0.10.0, three releases after the deprecation began. The July release also ends the assumption that intervals must be in memory: bed_map(), bed_intersect(), bed_subtract(), bed_coverage() and bed_window() accept a bigWig or bigBed path or URL where an interval table used to go.
◆ Where it's heading
Two arcs converge here. One is compatibility: min_overlap arrived with a deprecation warning in 0.9.0 and its default flipped from 0 to 1 in 0.10.0, so book-ended intervals are excluded by default as bedtools does, with the internal calculations in bed_closest() and friends deliberately left counting them. The other is the file-backed path, which grew out of the cpp11bigwig dependency adopted in 0.8.3 for read_bigwig() and re-exported in 0.9.0 — reading a file became querying one. Underneath, the C++ base keeps getting lighter: Rcpp swapped for cpp11, rlang cut to a single function, per-group memory copies removed from three verbs.
◆ Prediction
Only five verbs take a file argument today and bed_closest(), bed_glyph() and the statistical verbs do not, so extending the file-backed path across the rest of the API is the obvious follow-up. The deprecated tibble re-exports and the now-defunct n_fields argument suggest continued removal of the compatibility layer in the next minor release.
