What is RNiftyReg?

Medical image registration, maintained with unusual care for other people's conventions.

RNiftyReg wraps the NiftyReg C++ library for linear and non-linear registration of medical images in R. The releases in the window are all corrections rather than features: a serialisation bug in saveTransform(), a C++20 comparison warning, and a removed class member flagged by a compiler pre-release. The substantive item is 2.8.4, which fixed an image-flip bug when importing FSL-FLIRT transforms.

What is tidyaudit?

Pipeline provenance for tidyverse workflows, recording what changed at each step without keeping the data.

tidyaudit records lightweight metadata snapshots as data flows through a pipeline — row and column counts, NA counts, and structured diffs between any two points — without storing the data itself. Taps are operation-aware, so join, filter, and anti-join steps each report what that operation specifically did, and validation helpers cover join integrity, primary keys, and variable relationships. The trail can now be exported as a self-contained interactive HTML diagram or serialized to JSON or RDS.

Medical image registration, maintained with unusual care for other people's conventions.

◆ Current state

RNiftyReg wraps the NiftyReg C++ library for linear and non-linear registration of medical images in R. The releases in the window are all corrections rather than features: a serialisation bug in saveTransform(), a C++20 comparison warning, and a removed class member flagged by a compiler pre-release. The substantive item is 2.8.4, which fixed an image-flip bug when importing FSL-FLIRT transforms.

◆ Where it's heading

The package is stable and the maintenance work is characteristically about interoperability, correctly interpreting transforms written by other toolchains and staying clean against evolving C++ standards and compilers. The FLIRT flip fix is the clearest example: it required knowing an undocumented quirk of how another tool handles images with positive-determinant xforms. Several fixes originate from CRAN's compiler checks, and 2.8.5 finally retired a README section about upgrading from a release line now over ten years old.

◆ Prediction

Expect continued small releases tracking compiler and standards changes, with feature work arriving only if the underlying NiftyReg library moves.

Pipeline provenance for tidyverse workflows, recording what changed at each step without keeping the data.

◆ Current state

tidyaudit records lightweight metadata snapshots as data flows through a pipeline — row and column counts, NA counts, and structured diffs between any two points — without storing the data itself. Taps are operation-aware, so join, filter, and anti-join steps each report what that operation specifically did, and validation helpers cover join integrity, primary keys, and variable relationships. The trail can now be exported as a self-contained interactive HTML diagram or serialized to JSON or RDS.

◆ Where it's heading

The arc is from inspection to artifact. The first release made the trail something you print and read; 0.2.0 made it something you can hand to someone else or feed to another program, with the HTML export deliberately requiring no server and no Shiny. Reporting has been refined in the same direction, with a tabular changes block showing from-and-to values with row, column, and NA deltas. The remaining work in the window is defensive — a factor-handling path rebuilt because R-devel tightened what as.data.frame.table() accepts in row names.

◆ Prediction

With serialization and a standalone export in place, the natural next step is making trails comparable across runs rather than only across steps within one, though nothing in the entries commits to it yet.
