parglm vs rasterpic: at a glance
What is parglm?
Under a new maintainer, parglm traded raw speed work for glm parity and memory safety
parglm fits generalized linear models using parallel QR decomposition, targeting datasets where glm() is too slow. Tom Palmer took over maintenance at 0.1.8 in April 2026, and the package has released five times since — a burst of activity after a long quiet period. 0.2.0 in July 2026 is the first release to focus on correctness rather than throughput.
What is rasterpic?
rasterpic became an S3 generic and picked up stars support; the rest is upkeep
rasterpic georeferences ordinary images onto spatial objects, producing terra SpatRasters that can be plotted as basemaps or overlays. The package is small and its job is narrow. The meaningful recent change is 0.5.0, which turned rasterpic_img() into an S3 generic with methods per input class and added support for stars objects alongside sf and terra.

◆ Current state
parglm fits generalized linear models using parallel QR decomposition, targeting datasets where glm() is too slow. Tom Palmer took over maintenance at 0.1.8 in April 2026, and the package has released five times since — a burst of activity after a long quiet period. 0.2.0 in July 2026 is the first release to focus on correctness rather than throughput.
◆ Where it's heading
The arc runs from performance to trustworthiness. 0.1.9 was a large optimization release — deque-based task queues, fused memory passes, upper-triangle-only Fisher information, thread_local IDs — plus ecosystem integration with sandwich and gtsummary. 0.2.0 then fixed an out-of-bounds write triggered by small block_size values and a path where a non-finite working response could poison the QR decomposition, and brought response-type handling in line with glm().
◆ Prediction
With the memory-safety issues addressed and glm parity closed for binomial responses, further work is likely to extend family coverage or the benchmark suite rather than revisit the threading model. The C++17 requirement set at 0.1.8 gives room for more aggressive optimization if the maintainer returns to that.

rasterpic became an S3 generic and picked up stars support; the rest is upkeep
◆ Current state
rasterpic georeferences ordinary images onto spatial objects, producing terra SpatRasters that can be plotted as basemaps or overlays. The package is small and its job is narrow. The meaningful recent change is 0.5.0, which turned rasterpic_img() into an S3 generic with methods per input class and added support for stars objects alongside sf and terra.
◆ Where it's heading
The direction is broader input-class coverage inside the same single-function design, and tighter integration with the plotting ecosystem downstream. 0.3.0 renamed output layers to r/g/b/alpha specifically to stay compatible with tmap 4.0; 0.5.1 restored the RGB specification on masked and inverted output after it regressed, and moved errors and warnings to cli formatting. Releases are frequent but small.
◆ Prediction
With the generic in place, adding further input classes is now cheap, so that is the likely direction. The 0.5.1 regression on mask/inverse output suggests the RGB-specification path is the fragile part worth watching.
