What is glcdp?

glcdp reaches 1.0.0 with a stable schema contract behind its data explorer.

glcdp imports light-logger data packages published to the GLC standard, driven by declared schemas rather than format-specific readers. 0.9.3 added glc_explore(), a Shiny application for browsing the registry and exporting an annotated reproducible script. 1.0.0 promotes schema 3.0.2 to the default and primary stable import contract and makes schema-declared variable types and factor-level order drive the import itself.

What is jSDM?

Joint species distribution models in Gibbs-sampled C++, quiet since 2023.

jSDM fits joint species distribution models by Gibbs sampling, with the sampler written in C++ against GSL and Armadillo and exposed through binomial probit, binomial logit, Poisson log and Gaussian entry points. The 0.2 line extended it with species traits, constrained factor loadings and residual-association plots. The one entry since 2023 carries only a compare link.

6.3

glcdp reaches 1.0.0 with a stable schema contract behind its data explorer.

◆ Current state

glcdp imports light-logger data packages published to the GLC standard, driven by declared schemas rather than format-specific readers. 0.9.3 added glc_explore(), a Shiny application for browsing the registry and exporting an annotated reproducible script. 1.0.0 promotes schema 3.0.2 to the default and primary stable import contract and makes schema-declared variable types and factor-level order drive the import itself.

◆ Where it's heading

The package is serving two audiences from one model. Programmatic users get glc_collect(), extract_metadata() and add_metadata(), with imports that reject file groups whose factor labels or level order disagree. Interactive users get an Explorer that filters by device, wearing position, modality, role and data state, pages large inventories at 100 rows, and caches remote metadata for immutable revisions. Schemas 1.0.0 and 2.0.0 stay reachable as barebones legacy paths.

◆ Prediction

With 3.0.2 named the primary stable contract and the older schemas explicitly labelled legacy, retiring the barebones paths is the most likely next structural move. The notes give no indication of work beyond the current schema line.

J
jSDM
INFRA · APIS
0.0

Joint species distribution models in Gibbs-sampled C++, quiet since 2023.

◆ Current state

jSDM fits joint species distribution models by Gibbs sampling, with the sampler written in C++ against GSL and Armadillo and exposed through binomial probit, binomial logit, Poisson log and Gaussian entry points. The 0.2 line extended it with species traits, constrained factor loadings and residual-association plots. The one entry since 2023 carries only a compare link.

◆ Where it's heading

The package built out its model family quickly and then stopped: five of the six visible entries are stamped the same day as a backfilled archive, and the only later release says nothing about its contents. The direction the 0.2 line was heading, toward trait-mediated species effects and better convergence on latent variable models, has no visible continuation.

◆ Prediction

The feed does not support a confident prediction; the latest entry publishes no notes, so whether the package is still developing or only being kept CRAN-clean cannot be read from it.
