Retool
Retool is retiring standalone Assist while folding the same capability into the app builder.
A side-by-side editorial comparison of dqcheckr and RNiftyReg — release velocity, themes, recent moves, and the top alternatives to consider.
dqcheckr adds drift analysis, then removes the YAML a user had to hand-write.
dqcheckr runs configurable data-quality checks over files and DuckDB tables, driven by YAML dataset configs and recording results as snapshots. The 0.2.0 release added the ability to compare two historical snapshots and report per-column statistical drift, schema changes and trend charts, extending the tool from point-in-time checking into change over time. The most recent tag, 0.3.0, attacks the other friction point by generating the config itself from a sniff pass over the data.
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.

Both moves point the same way: reduce what the operator has to write and know. Config generation removes the hand-authored YAML that gated first use, list_runs() and validate_config() make an existing setup inspectable, and the snapshot comparison turns accumulated run history into a second product surface. Check coverage keeps widening underneath — outlier detection, composite keys, row-count and file-size ceilings — and the reporting layer moved from rmarkdown to Quarto, with existing 0.1.x databases auto-migrated on first run.
Expect the generated configs and the drift reports to converge, so a sniffed config can seed thresholds from the snapshot history rather than from defaults, plus continued growth in the numbered QC check catalogue.
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.
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.
Expect continued small releases tracking compiler and standards changes, with feature work arriving only if the underlying NiftyReg library moves.
