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 surveycore?

surveycore declared its API stable with every survey design type covered.

surveycore is the estimation engine of a two-package survey stack, handling design objects and variance estimation while surveytidy supplies the dplyr verbs on top. The June release marks it 1.0.0 and states the API is complete and stable across Taylor series linearization, replicate weights, two-phase and non-probability designs, with means, totals, frequencies, quantiles, ratios, correlations, regression, t-tests, ANOVA and effective sample size all in place.

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.

0.0

surveycore declared its API stable with every survey design type covered.

◆ Current state

surveycore is the estimation engine of a two-package survey stack, handling design objects and variance estimation while surveytidy supplies the dplyr verbs on top. The June release marks it 1.0.0 and states the API is complete and stable across Taylor series linearization, replicate weights, two-phase and non-probability designs, with means, totals, frequencies, quantiles, ratios, correlations, regression, t-tests, ANOVA and effective sample size all in place.

◆ Where it's heading

The last months before 1.0.0 were spent making the awkward designs behave like the ordinary ones. Non-probability designs gained jackknife replicate schemes and got their bootstrap repweights routed through the replicate-weight variance estimator in survey_glm(), matching every other estimation function. The survey_collection abstraction — several surveys treated as one pseudo-data-frame — was tightened rather than extended: divergent grouping across members now errors instead of stitching a patchwork with bind_rows(), and the missing-variable argument was renamed and given a stored default on the collection itself. A documentation audit before 1.0.0 turned up six dispatch and print bugs and corrections across forty-plus files, which is the kind of thing that surfaces when an API is being frozen rather than extended.

◆ Prediction

A declared-stable API means the next releases should be additive or corrective rather than breaking, and the pre-1.0.0 pattern of breaking renames should stop. The tight version pinning between the two packages means surveytidy releases will keep following surveycore's.
