What is mmconvert?

A single-purpose mouse map interpolator that solved its problem in 2023 and has coasted since

mmconvert does one thing: interpolate between GRCm39 physical positions and the revised Cox genetic map for mouse MUGA array markers. The substantive work all landed in a burst across 2021-2023 — the initial function, the GRCm39 annotation dataset, cross2_to_grcm39(), the recomputed Cox maps and their smoothed replacement. Everything since is upkeep: a warning-message fix in 0.12, and 0.14 is a test adjustment to silence a CRAN Note with no code change at all.

What is quanteda?

Text analysis in R keeps optimising its token internals — and builds a path out to torch

quanteda is a mature framework for quantitative text analysis in R. Since the 4.0 rewrite around external-pointer tokens objects, releases have concentrated on the internals: recompilation control, memory reduction on concatenation, type-table consistency between tokens and dfm objects. The newest release adds tokens_recompile() for explicit ID reassignment, stops query functions from recompiling implicitly, and returns dense rather than sparse tensors from as.tensor() with arguments passed through to torch.

◆ Current state

mmconvert does one thing: interpolate between GRCm39 physical positions and the revised Cox genetic map for mouse MUGA array markers. The substantive work all landed in a burst across 2021-2023 — the initial function, the GRCm39 annotation dataset, cross2_to_grcm39(), the recomputed Cox maps and their smoothed replacement. Everything since is upkeep: a warning-message fix in 0.12, and 0.14 is a test adjustment to silence a CRAN Note with no code change at all.

◆ Where it's heading

The package has reached the natural end state of a reference-data converter — the reference data stopped moving, so the package stopped moving. Releases now arrive roughly annually and exist to keep CRAN checks green. The 0.14 release shipped the same day as sibling qtl2convert 0.36, confirming these are batch maintenance passes across the maintainer's packages rather than independent development.

◆ Prediction

Without a new mouse genome build or a revised Cox map, the next release is likely another CRAN-check accommodation rather than new functionality.

Text analysis in R keeps optimising its token internals — and builds a path out to torch

◆ Current state

quanteda is a mature framework for quantitative text analysis in R. Since the 4.0 rewrite around external-pointer tokens objects, releases have concentrated on the internals: recompilation control, memory reduction on concatenation, type-table consistency between tokens and dfm objects. The newest release adds tokens_recompile() for explicit ID reassignment, stops query functions from recompiling implicitly, and returns dense rather than sparse tensors from as.tensor() with arguments passed through to torch.

◆ Where it's heading

Two threads run in parallel. The dominant one is performance and correctness housekeeping on the tokens_xptr representation introduced in 4.0 — each release closes another case where the external-pointer path diverged from the plain tokens path. The quieter thread points outward: as.matrix() returning a document-by-position integer matrix and as.tensor() handing off to torch::torch_tensor() make the tokenised corpus directly consumable by neural models rather than only by quanteda's own bag-of-words machinery.

◆ Prediction

The tensor and matrix export path is the least mature part of the surface and gained arguments in this release rather than settling, so expect further work there before the token internals change again.
