What is rncl?

A phylogenetics parser on life support, shipping only what CRAN's compilers demand.

rncl wraps the Nexus Class Library so R can read Newick and NEXUS tree files. Every release since 2016 has been custodial: 0.8.9 exists solely to pull upstream NCL changes so the bundled C++ compiles under the C++20 standard. No user-facing function has changed in close to a decade.

What is TwoSampleMR?

The flagship Mendelian randomization package is auditing its own estimators, one bootstrap at a time.

TwoSampleMR is the MRC-IEU package for two-sample Mendelian randomization against OpenGWAS. Its 2026 releases are a sustained correctness review rather than feature work: 0.7.9 fixed bootstrap standard errors in mr_mode() and mr_rucker_bootstrap() that had been inflated since v0.6.30, and repaired two Rucker functions that were returning malformed objects. Point estimates were not affected by the bootstrap bug.

2.5

A phylogenetics parser on life support, shipping only what CRAN's compilers demand.

◆ Current state

rncl wraps the Nexus Class Library so R can read Newick and NEXUS tree files. Every release since 2016 has been custodial: 0.8.9 exists solely to pull upstream NCL changes so the bundled C++ compiles under the C++20 standard. No user-facing function has changed in close to a decade.

◆ Where it's heading

The release cadence tracks toolchain deprecations rather than user demand: gcc 12 removing binary_function in 2022, a deprecated Rcpp call in 2025, C++20 in 2026. The package is maintained as a stable parsing dependency for phylogenetics tooling, and the goal visible in these entries is keeping it installable, not extending it.

◆ Prediction

Expect the next release only when a compiler or CRAN policy change breaks the build again; nothing in these entries points to new parsing features.

0.0

The flagship Mendelian randomization package is auditing its own estimators, one bootstrap at a time.

◆ Current state

TwoSampleMR is the MRC-IEU package for two-sample Mendelian randomization against OpenGWAS. Its 2026 releases are a sustained correctness review rather than feature work: 0.7.9 fixed bootstrap standard errors in mr_mode() and mr_rucker_bootstrap() that had been inflated since v0.6.30, and repaired two Rucker functions that were returning malformed objects. Point estimates were not affected by the bootstrap bug.

◆ Where it's heading

The pattern across these releases is a package being read line by line — a copy-paste weight vector in ldsc_rg(), chunking that produced zero splits for short SNP lists, penalisation recycled across the wrong SNPs, dead code paths removed, and regression tests added behind each fix. Alongside it runs a mechanical modernization pass: seq_len() for loop indices, tidyr in place of reshape2, current ggplot2 idioms, and the OpenGWAS URL migration. Feature work is limited to forest plot presentation.

◆ Prediction

Expect the audit to continue through the remaining bootstrap and jackknife routines, with releases staying in the 0.7.x patch range and each fix arriving with its own regression test.
