What is jSDM?

Joint species distribution models in Gibbs-sampled C++, quiet since 2023.

jSDM fits joint species distribution models by Gibbs sampling, with the sampler written in C++ against GSL and Armadillo and exposed through binomial probit, binomial logit, Poisson log and Gaussian entry points. The 0.2 line extended it with species traits, constrained factor loadings and residual-association plots. The one entry since 2023 carries only a compare link.

What is vcfR?

A genomics workhorse whose visible release feed stops dead in mid-2020.

vcfR reads, manipulates and visualises VCF files, the standard format for genomic variant calls, and bridges them into R population-genetics classes such as genind, genlight and DNAbin. The three entries available here all come from the first half of 2020 and stop there, so the feed shows the state of the package six years ago rather than today.

jSDM vs vcfR: editorial side-by-side

J
jSDM
INFRA · APIS
0.0

Joint species distribution models in Gibbs-sampled C++, quiet since 2023.

◆ Current state

jSDM fits joint species distribution models by Gibbs sampling, with the sampler written in C++ against GSL and Armadillo and exposed through binomial probit, binomial logit, Poisson log and Gaussian entry points. The 0.2 line extended it with species traits, constrained factor loadings and residual-association plots. The one entry since 2023 carries only a compare link.

◆ Where it's heading

The package built out its model family quickly and then stopped: five of the six visible entries are stamped the same day as a backfilled archive, and the only later release says nothing about its contents. The direction the 0.2 line was heading, toward trait-mediated species effects and better convergence on latent variable models, has no visible continuation.

◆ Prediction

The feed does not support a confident prediction; the latest entry publishes no notes, so whether the package is still developing or only being kept CRAN-clean cannot be read from it.

0.0

A genomics workhorse whose visible release feed stops dead in mid-2020.

◆ Current state

vcfR reads, manipulates and visualises VCF files, the standard format for genomic variant calls, and bridges them into R population-genetics classes such as genind, genlight and DNAbin. The three entries available here all come from the first half of 2020 and stop there, so the feed shows the state of the package six years ago rather than today.

◆ Where it's heading

Within that window the direction is unmistakably consolidation, not growth. 1.9.0 pushed error handling down into the C++ layer that actually reads the VCF so failures surface earlier and shared files stop tripping a readability pre-check, tightened class checks, and added conversion options. The two releases after it exist only to keep pace with R 4.0.0 and dplyr 1.0.0. Any development after June 2020 is not visible in this feed, so the current trajectory cannot be read from it.

◆ Prediction

No prediction can be grounded in these entries — the feed has been silent for six years, which points at a stale or broken source rather than at a package that stopped.

Frequently asked questions

What is the difference between jSDM and vcfR?

They serve adjacent needs but don't currently overlap on shipped themes. jSDM and vcfR 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 jSDM better than vcfR?

Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. jSDM and vcfR are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). For your specific use case, the alternatives sections above list other Infra & APIs products to evaluate alongside.
