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 constants?

The R package for CODATA constants rebuilt its symbol table on NIST's naming so future updates stop being hand work.

constants exposes the CODATA recommended values of the physical constants to R, as a data frame plus symbol lists that carry units, uncertainties, or both. The package reached 1.0.0 on the 2018 CODATA release and has shipped once since, purely to track a units package update. Its surface is small and its release cadence is bound to CODATA, which revises every few years.

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 R package for CODATA constants rebuilt its symbol table on NIST's naming so future updates stop being hand work.

◆ Current state

constants exposes the CODATA recommended values of the physical constants to R, as a data frame plus symbol lists that carry units, uncertainties, or both. The package reached 1.0.0 on the 2018 CODATA release and has shipped once since, purely to track a units package update. Its surface is small and its release cadence is bound to CODATA, which revises every few years.

◆ Where it's heading

The direction set at 1.0.0 was to stop being a curated convenience wrapper and become a mechanical mirror of NIST. Hand-crafted symbol names were replaced with NIST's own ASCII symbols, categories adopted NIST's, and uncertainty switched from relative to absolute — all framed by the maintainer as necessary to make future CODATA updates routine. On top of that the package gained a correlation matrix and optional integration with the quantities package, moving it from a lookup table toward something that can propagate uncertainty.

◆ Prediction

Having rebuilt the symbol table specifically so CODATA revisions become mechanical, the next substantive release most likely tracks a new CODATA dataset rather than adding API. The experimental correlated-value support, disabled by default at 1.0.0, is the one part these entries flag as unfinished.
