What is crandep?

Half CRAN dependency scraper, half extreme-value modelling kit — and the scraper half keeps finding bugs.

crandep does two jobs that rarely share a package: it harvests the CRAN dependency network, and it fits power-law and extreme-value mixture models to the resulting degree distributions. The 2024 releases were all model work — profile posteriors, wrappers, a constrained variant, a TZP-power-law mixture between the two- and three-component models. The 2025 releases are entirely the other half, fixing what the harvester was silently getting wrong.

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.

crandep vs vcfR: editorial side-by-side

Half CRAN dependency scraper, half extreme-value modelling kit — and the scraper half keeps finding bugs.

◆ Current state

crandep does two jobs that rarely share a package: it harvests the CRAN dependency network, and it fits power-law and extreme-value mixture models to the resulting degree distributions. The 2024 releases were all model work — profile posteriors, wrappers, a constrained variant, a TZP-power-law mixture between the two- and three-component models. The 2025 releases are entirely the other half, fixing what the harvester was silently getting wrong.

◆ Where it's heading

The modelling side has settled into a family of mixtures with matching wrapper and profile-posterior functions, and has not gained a new component since mid-2024. Attention has shifted to data quality in the scraper, where two consecutive releases dealt with the same class of problem: rows that should not exist because of trailing commas in CRAN's own metadata, and rows that should exist but did not because orphan packages have no edges. For a package whose science is degree distributions, missing isolated nodes is a modelling error, not a formatting one.

◆ Prediction

Expect further hardening against CRAN metadata quirks in the harvesting functions; the mixture-model side looks feature-complete and is likely to stay quiet unless a new component model is published.

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.
