coga vs pr2database
A side-by-side editorial comparison of coga and pr2database — release velocity, themes, recent moves, and the top alternatives to consider.
coga vs pr2database: at a glance
What is coga?
A gamma-convolution density package that reached completion in 2018 and has coasted since.
coga computes densities, distribution functions and random numbers for convolutions of gamma distributions, with the numerical work in C++ through Rcpp. It has been feature-complete since 1.0.0 in 2018, and every release in the seven years since has been maintenance: a documentation alias for CRAN, a compiler warning, a maintainer email change, and an Rcpp update requiring Rf_error calls to be guarded. The one functional addition in that period, in 1.1.0, was an unexported function added explicitly for research use.
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.

coga
0.0INFRA · APIS
A gamma-convolution density package that reached completion in 2018 and has coasted since.
◆ Current state
coga computes densities, distribution functions and random numbers for convolutions of gamma distributions, with the numerical work in C++ through Rcpp. It has been feature-complete since 1.0.0 in 2018, and every release in the seven years since has been maintenance: a documentation alias for CRAN, a compiler warning, a maintainer email change, and an Rcpp update requiring Rf_error calls to be guarded. The one functional addition in that period, in 1.1.0, was an unexported function added explicitly for research use.
◆ Where it's heading
This is a finished package being kept alive rather than developed. The releases track external pressure exactly: CRAN documentation requirements, compiler warnings, Rcpp API changes. Its maintenance is visibly shared with smam, the same maintainer's animal-movement package, which received the same email update, the same format-security fix and the same Rcpp guard within a minute or twenty of coga each time. Neither package is being extended; both are being kept installable.
◆ Prediction
Expect nothing but CRAN and toolchain maintenance, arriving whenever Rcpp or R's check requirements change, and arriving alongside smam. There is no signal in these entries of planned functional work.
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.

Frequently asked questions
What is the difference between coga and pr2database?
They serve adjacent needs but don't currently overlap on shipped themes. coga and pr2database are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.
Is coga better than pr2database?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. coga and pr2database are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
