plogr vs RNifti: at a glance
What is plogr?
A logging header for Rcpp packages that sat untouched for nine years, then changed how it switches on
plogr ships a stripped build of the plog C++ logging library as an R package, so other packages with C++ code can log through REprintf() and have output land in the R console rather than stdout. It is a header-only dependency with no R-level API to speak of. Three releases in September 2016 established it; the next arrived in November 2025.
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.

◆ Current state
plogr ships a stripped build of the plog C++ logging library as an R package, so other packages with C++ code can log through REprintf() and have output land in the R console rather than stdout. It is a header-only dependency with no R-level API to speak of. Three releases in September 2016 established it; the next arrived in November 2025.
◆ Where it's heading
There is almost no trajectory to read here, which is itself the finding — the package was finished in a week and stayed finished. The 2025 release is the first change in nine years and it tightens the activation contract: logging now does nothing unless PLOGR_ENABLE is defined at compile time, so packages depending on it get silence by default rather than unexpected output. A GCC-specific fix for function names in multi-argument template classes lands alongside.
◆ Prediction
With the activation macro now explicit, dependent packages that assumed logging was on will need to define it; beyond that the entries give no basis for expecting further development.

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.
