What is camtraptor?

A camera-trap data reader converging on the Camtrap DP standard, one exchange field at a time.

camtraptor reads Camera Trap Data Packages and turns them into analysis-ready tables for R users. The recent releases have been about what those tables carry: get_record_table() now returns deployment coordinates plus clock and solar time in radians, and get_custom_effort() reports effort per deployment rather than pooled. Earlier work went into reading Camtrap DP files written by other tools.

What is tulpa?

The 0.0.x train stops at CRAN: tulpa's engine ships to the ecosystem it already anchors.

tulpa is the C++/R Bayesian spatial inference engine sitting under gcol33's family of ecological occupancy packages, tagging 0.0.x releases several times a week. 0.1.0 is its first CRAN release, and the notes state outright that the engine surface is unchanged from 0.0.198 — the work is packaging discipline: local T bindings rebound to n_t/n_times, OpenMP teams capped under R CMD check, the pkgdown deploy narrowed, an aspell dictionary added. The window behind it splits between the S3 generics conversion and numerical-correctness work in the nested-Laplace grid.

0.0

A camera-trap data reader converging on the Camtrap DP standard, one exchange field at a time.

◆ Current state

camtraptor reads Camera Trap Data Packages and turns them into analysis-ready tables for R users. The recent releases have been about what those tables carry: get_record_table() now returns deployment coordinates plus clock and solar time in radians, and get_custom_effort() reports effort per deployment rather than pooled. Earlier work went into reading Camtrap DP files written by other tools.

◆ Where it's heading

The package is moving from format plumbing toward analysis convenience. The 2023-2024 releases were almost entirely about correctly ingesting Camtrap DP 1.0 and packages produced by the GBIF IPT; the 2025 pair instead adds columns ecologists would otherwise compute themselves. Releases come in bursts tied to specific issue reports, with long gaps between.

◆ Prediction

Expect continued issue-driven column and argument additions to the get_* family; nothing in these entries points to a change in the underlying reader.

The 0.0.x train stops at CRAN: tulpa's engine ships to the ecosystem it already anchors.

◆ Current state

tulpa is the C++/R Bayesian spatial inference engine sitting under gcol33's family of ecological occupancy packages, tagging 0.0.x releases several times a week. 0.1.0 is its first CRAN release, and the notes state outright that the engine surface is unchanged from 0.0.198 — the work is packaging discipline: local T bindings rebound to n_t/n_times, OpenMP teams capped under R CMD check, the pkgdown deploy narrowed, an aspell dictionary added. The window behind it splits between the S3 generics conversion and numerical-correctness work in the nested-Laplace grid.

◆ Where it's heading

Two moves in nine days point at the same destination: the generics conversion made tulpa extensible by downstream packages, and CRAN admission makes it installable by them. The current cadence — several tags a week, some existing only to record a measurement that produced no code change — does not survive CRAN's submission overhead, so the release rhythm has to slow whether or not the project intends it. The correctness work still clusters on the joint nested-Laplace driver, and 0.1.0 extends the same diagnostics habit with .NL_AXIS_SD_REASONS, a closed vocabulary for an outer axis whose grid does not contain its own posterior mode.

◆ Prediction

Expect tulpaObs to follow tulpa onto CRAN, since it is the consumer whose registrations the engine has spent this window unblocking, and expect the version line to move in larger, less frequent steps now that each one carries a submission.
