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.

What is UCell?

A rank-based gene signature scorer that has grown by adapting to whatever object format single-cell R uses next

UCell scores gene signatures in single-cell data using a rank-based metric that is robust to dataset composition. Its release history reads as a sequence of ecosystem accommodations: Bioconductor submission in 2.0, SmoothKNN() for k-nearest-neighbor smoothing of scores in 2.2, smoothing applied directly to expression slots in 2.4, Seurat v5 assay compatibility in 2.6, multi-layer Seurat v5 objects in 2.8, and a missing_genes parameter in 2.14 that lets callers impute or skip signature genes absent from the data. Version 2.16 tracks Bioconductor 3.23 and points at a new publication and a Python implementation, pyUCell.

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.

A rank-based gene signature scorer that has grown by adapting to whatever object format single-cell R uses next

◆ Current state

UCell scores gene signatures in single-cell data using a rank-based metric that is robust to dataset composition. Its release history reads as a sequence of ecosystem accommodations: Bioconductor submission in 2.0, SmoothKNN() for k-nearest-neighbor smoothing of scores in 2.2, smoothing applied directly to expression slots in 2.4, Seurat v5 assay compatibility in 2.6, multi-layer Seurat v5 objects in 2.8, and a missing_genes parameter in 2.14 that lets callers impute or skip signature genes absent from the data. Version 2.16 tracks Bioconductor 3.23 and points at a new publication and a Python implementation, pyUCell.

◆ Where it's heading

Two threads run through this. The scoring algorithm itself has barely changed — the rank-based core is stable, and 2.14's reformatting to gene indices rather than string matching is a speed change, not a method change. What does change constantly is object-format compatibility, which is the tax of living between Seurat and SingleCellExperiment. The pyUCell reference in 2.16 is the first sign of the method reaching beyond R, though these notes say nothing about its scope.

◆ Prediction

The cadence is locked to Bioconductor's twice-yearly release train, so the next version will most likely accompany Bioconductor 3.24 with whatever Seurat or SingleCellExperiment changes it brings.
