ggh4x vs pr2database
A side-by-side editorial comparison of ggh4x and pr2database — release velocity, themes, recent moves, and the top alternatives to consider.
ggh4x vs pr2database: at a glance
What is ggh4x?
Handed its axis and legend guides to ggplot2 and legendry, and kept the facets
ggh4x is a set of ggplot2 extensions — nested and manual facets, per-facet scales, forced panel sizes, and statistics such as stat_difference() and stat_rle(). Its guide functions, once a substantial part of the package, are deprecated: 0.3.0 redirected users to ggplot2's own guide arguments and to the legendry package, and 0.3.1 made the deprecated functions return plain equivalents. What remains as this package's own territory is facetting and panel layout.
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.

Handed its axis and legend guides to ggplot2 and legendry, and kept the facets
◆ Current state
ggh4x is a set of ggplot2 extensions — nested and manual facets, per-facet scales, forced panel sizes, and statistics such as stat_difference() and stat_rle(). Its guide functions, once a substantial part of the package, are deprecated: 0.3.0 redirected users to ggplot2's own guide arguments and to the legendry package, and 0.3.1 made the deprecated functions return plain equivalents. What remains as this package's own territory is facetting and panel layout.
◆ Where it's heading
The handover was signalled well in advance. Version 0.2.5 set the guides' lifecycle to 'questioning' and said outright they might migrate to a new package once ggplot2 overhauled its guide system, and 0.3.0 executed that eighteen months later. Much of the rest of the changelog is anticipatory compatibility work for upcoming ggplot2 releases, the standing cost of being an extension package. Releases carry playful codenames that say nothing about their contents.
◆ Prediction
The deprecated guide functions are scheduled for removal in the next non-hotfix release, so expect that next; continued work should concentrate on facets and panel sizing, the areas neither ggplot2 nor legendry has absorbed.
pr2database
0.0INFRA · APIS
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.
