What is RNifti?

The C++ layer under R's neuroimaging stack, closing the gaps where images stopped acting like arrays

RNifti reads and writes NIfTI and ANALYZE medical image files, exposing them to R through an internalImage class that keeps pixel data on the C++ side until it is needed. It is infrastructure: other neuroimaging packages depend on it, and much of its release history is driven by their bug reports. Recent work has been about making that lazy image type behave like a normal R array without giving up the memory advantage.

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.

The C++ layer under R's neuroimaging stack, closing the gaps where images stopped acting like arrays

◆ Current state

RNifti reads and writes NIfTI and ANALYZE medical image files, exposing them to R through an internalImage class that keeps pixel data on the C++ side until it is needed. It is infrastructure: other neuroimaging packages depend on it, and much of its release history is driven by their bug reports. Recent work has been about making that lazy image type behave like a normal R array without giving up the memory advantage.

◆ Where it's heading

Two threads run through these releases. One extends what the package can represent — RGB arrays, complex datatypes, JSON sidecar metadata — steadily widening the file and type surface it covers. The other closes semantic holes in the deferred-loading design, where R would silently fall back on character methods because the image class had no method of its own. The 1.9.0 work is the clearest example, and it is careful to keep the memory benefit by pushing summaries into C++ rather than materialising an array.

◆ Prediction

The JSON sidecar support is flagged as R-only for now, which makes exposing it through the C++ API the most likely next step.

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.
