What is dwctaxon?

A Darwin Core validator that went quiet for two years, then surfaced only to raise its R floor

dwctaxon edits and validates taxonomic data held in Darwin Core format, enforcing the referential rules that make a taxonomic database internally consistent. Its last real functional change was 2.0.3 in December 2023, which loosened an over-strict uniqueness requirement in column matching. The most recent entry is a development build two years later that does nothing but set a minimum R version and bump Roxygen.

What is poissonreg?

poissonreg gave its models away to parsnip and kept the glue — now it just keeps glmnet honest.

poissonreg is a tidymodels extension that wires Poisson and zero-inflated count regression into the parsnip interface. Its defining event was giving up ownership: the model definition functions moved into parsnip itself, leaving this package as engine bindings and prediction plumbing. The current dev release is entirely correctness and hygiene work — glmnet predictions now default to mean counts rather than the linear predictor, and single-observation prediction works at last.

A Darwin Core validator that went quiet for two years, then surfaced only to raise its R floor

◆ Current state

dwctaxon edits and validates taxonomic data held in Darwin Core format, enforcing the referential rules that make a taxonomic database internally consistent. Its last real functional change was 2.0.3 in December 2023, which loosened an over-strict uniqueness requirement in column matching. The most recent entry is a development build two years later that does nothing but set a minimum R version and bump Roxygen.

◆ Where it's heading

The visible arc is a package converging on correctness rather than growing. The 2.0.3 change is the most consequential: matching a reference column no longer demands that every value in it be unique, only that the matched values be — which is what makes dct_fill_col() usable on real taxonomic tables where scientificName legitimately repeats. Around it sits compliance work: an internet-connection and URL check added purely to satisfy CRAN policy, and examples reworked to restore user settings and skip deliberate errors.

◆ Prediction

The 2.0.3.9001 development stamp with an R >= 4.2.0 requirement suggests a 2.0.4 release is being prepared, most likely as maintenance rather than new validation rules. The two-year gap makes any stronger claim unsupported by the feed.

poissonreg gave its models away to parsnip and kept the glue — now it just keeps glmnet honest.

◆ Current state

poissonreg is a tidymodels extension that wires Poisson and zero-inflated count regression into the parsnip interface. Its defining event was giving up ownership: the model definition functions moved into parsnip itself, leaving this package as engine bindings and prediction plumbing. The current dev release is entirely correctness and hygiene work — glmnet predictions now default to mean counts rather than the linear predictor, and single-observation prediction works at last.

◆ Where it's heading

Release cadence has collapsed from yearly to a four-year gap between 1.0.1 and the current development version, and the content has shifted from features to deduplication against parsnip — copied helper functions replaced by the upstream originals, obsolete generic registrations removed, tests migrated to the shared extension-package pattern. This is what a stabilized tidymodels satellite looks like: the interface lives upstream, and the package's job is to not drift from it.

◆ Prediction

The dev version's accumulated fixes point to a CRAN release of 1.0.2 as the next move, with content limited to the glmnet prediction corrections rather than any new engine or model type.
