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 tmap?

Two years after a from-scratch rewrite, tmap is filling in the layers v4 promised.

tmap draws thematic maps in R across static and interactive modes. The 4.0 rewrite replaced the layer syntax with explicit visual variables, scales, legends and charts, and opened the package to extensions; the 4.x line since has been steady capability fill-in. The 4.4 release adds tm_circles with fixed unit-based radii, a blend argument on every layer, and hitboxes so small objects stay clickable in view mode.

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

Two years after a from-scratch rewrite, tmap is filling in the layers v4 promised.

◆ Current state

tmap draws thematic maps in R across static and interactive modes. The 4.0 rewrite replaced the layer syntax with explicit visual variables, scales, legends and charts, and opened the package to extensions; the 4.x line since has been steady capability fill-in. The 4.4 release adds tm_circles with fixed unit-based radii, a blend argument on every layer, and hitboxes so small objects stay clickable in view mode.

◆ Where it's heading

The extension mechanism introduced in 4.0 is where the interesting work is migrating: PMTiles support arrived through a separate experimental tmap.sources package, mode cycling became configurable via tmap_mode_pool() so packages like tmap.mapgl can register themselves, and shiny dispatch methods were added specifically to let other modes integrate. The core package is increasingly a rendering contract that satellite packages plug into.

◆ Prediction

Expect more rendering backends to land as sibling packages rather than in tmap itself, with the core continuing to absorb the dispatch and mode-management plumbing they need.
