What is ijtiff?

A TIFF reader for scientific imaging that spent its recent releases shedding weight and fixing memory bugs.

ijtiff reads and writes TIFF files the way ImageJ writes them, which ordinary R TIFF readers get wrong — multi-channel, multi-frame, and unusual bit depths. The 3.1.x line is dominated by memory correctness in the C tag-handling layer, alongside dropping the large imager dependency from the display path. Cadence is sporadic, with multi-year gaps.

What is USAboundaries?

Seven years dormant, then two releases dragging every census boundary from 2020 to 2024

USAboundaries supplies contemporary and historical US boundary data — states, counties, congressional districts, cities, ZIP code tabulation areas — as sf objects, with the bulk data held in a companion USAboundariesData package. After a gap running from 2018 to late 2025, two releases a month apart refreshed the contemporary census vintage from 2020 to 2024: 0.5.0 covered everything except states, and 0.5.1 finished the job.

ijtiff vs USAboundaries: editorial side-by-side

I
ijtiff
ANALYTICS
0.0

A TIFF reader for scientific imaging that spent its recent releases shedding weight and fixing memory bugs.

◆ Current state

ijtiff reads and writes TIFF files the way ImageJ writes them, which ordinary R TIFF readers get wrong — multi-channel, multi-frame, and unusual bit depths. The 3.1.x line is dominated by memory correctness in the C tag-handling layer, alongside dropping the large imager dependency from the display path. Cadence is sporadic, with multi-year gaps.

◆ Where it's heading

Two threads run through the window. The C layer is being hardened — memory leaks in tag handling, buffer cleanup, PROTECT errors, validation of malformed files — which is the kind of work that surfaces when a package gets run against real-world files at volume. Separately, the R layer is shedding dependencies, with base graphics replacing imager for display. Both make the package cheaper and safer to depend on rather than more capable.

◆ Prediction

Expect continued C-level correctness work rather than format features, since three of the last three substantive releases were memory or compiler fixes.

Seven years dormant, then two releases dragging every census boundary from 2020 to 2024

◆ Current state

USAboundaries supplies contemporary and historical US boundary data — states, counties, congressional districts, cities, ZIP code tabulation areas — as sf objects, with the bulk data held in a companion USAboundariesData package. After a gap running from 2018 to late 2025, two releases a month apart refreshed the contemporary census vintage from 2020 to 2024: 0.5.0 covered everything except states, and 0.5.1 finished the job.

◆ Where it's heading

For a data package the release cycle is the data vintage, and the 0.3.0 split into a separate data package was designed precisely so those refreshes would not require a code release. That the 2024 update still arrived as two package versions seven years later says the mechanism is being used sparingly. Nothing in the feed shows work on the API itself since us_cities() gained an sf return type and a states argument in 2018.

◆ Prediction

The next release is most likely another vintage refresh when the census data moves again, rather than new geographies or functions. The split of 0.5.0 and 0.5.1 suggests state boundaries are handled on a separate path from the rest and may lag again.
