What is lightr?

Reorganised its parsers by vendor, then opened the parser slot to users.

lightr reads spectrometry files from the proprietary formats that instrument vendors ship, and its recent releases have been about the structure of that parser collection rather than adding one more format. Version 2.0.0 renamed every low-level parser from lr_parse_<extension>() to lr_parse_<brand>_<extension>(), a breaking change made specifically so two vendors can share a file extension without colliding, and restored binary parsing for Avantes AvaSoft 8.4 using vendor-supplied format documentation. Version 2.1.0 follows through by exposing a parser argument on the high-level functions.

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.

Reorganised its parsers by vendor, then opened the parser slot to users.

◆ Current state

lightr reads spectrometry files from the proprietary formats that instrument vendors ship, and its recent releases have been about the structure of that parser collection rather than adding one more format. Version 2.0.0 renamed every low-level parser from lr_parse_<extension>() to lr_parse_<brand>_<extension>(), a breaking change made specifically so two vendors can share a file extension without colliding, and restored binary parsing for Avantes AvaSoft 8.4 using vendor-supplied format documentation. Version 2.1.0 follows through by exposing a parser argument on the high-level functions.

◆ Where it's heading

The package is moving from a fixed set of formats it knows about to a dispatch system users can extend. The brand-qualified naming and the parser argument are two halves of the same design: name parsers unambiguously, then let callers select or supply one. Alongside that runs steady attention to metadata fidelity — measurement timestamps, checksum verification against tampering, and timezone handling that survived upstream tzdata removing legacy codes.

◆ Prediction

Expect additional vendor parsers to arrive under the new brand-qualified scheme, and the custom-parser path to absorb formats the maintainers do not want to support directly. The entries do not name specific instruments planned next.

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.
