What is chattr?

chattr deleted every LLM integration it had written and outsourced the lot to ellmer

chattr puts a large language model inside the RStudio IDE, either through a Shiny app or directly at the console. As of 0.3.0 it no longer talks to any model provider itself: all integration goes through ellmer, and the hand-written OpenAI, Databricks and LlamaGPT backends were removed. The package's supported model list is now whatever ellmer supports, and the Shiny app streams responses through ellmer rather than managing a background process.

What is metatools?

SDTM supplemental-qualifier merging got sturdier, then the package went quiet for two years.

metatools provides the utilities that build and check SDTM and ADaM datasets against their metadata in the pharmaverse. The 0.1.6 release in July 2024 is the substantive one: combine_supp() learned to handle zero-row supplemental data, to refuse QNAM columns already present in the source, and to route multiple QNAM values to the same IDVAR, alongside enhanced controlled-terminology checks and record-uniqueness verification. Nothing has shipped since.

chattr deleted every LLM integration it had written and outsourced the lot to ellmer

◆ Current state

chattr puts a large language model inside the RStudio IDE, either through a Shiny app or directly at the console. As of 0.3.0 it no longer talks to any model provider itself: all integration goes through ellmer, and the hand-written OpenAI, Databricks and LlamaGPT backends were removed. The package's supported model list is now whatever ellmer supports, and the Shiny app streams responses through ellmer rather than managing a background process.

◆ Where it's heading

The first two releases show why that happened. Each provider brought its own error formats, token discovery and response handling, and 0.2.0 is largely a list of per-provider repairs — OpenAI error parsing, Copilot token discovery and model defaults, a new Databricks foundation model backend. Maintaining that surface scales linearly with the number of providers, and the pivot to ellmer trades it for a single dependency. The cost shows up immediately in 0.3.1, which exists solely to absorb a change in ellmer's token object.

◆ Prediction

Expect chattr's releases to now track ellmer's, as 0.3.1 already does, with the package's own work concentrating on the IDE experience rather than model connectivity. New provider support will arrive without a chattr release at all.

SDTM supplemental-qualifier merging got sturdier, then the package went quiet for two years.

◆ Current state

metatools provides the utilities that build and check SDTM and ADaM datasets against their metadata in the pharmaverse. The 0.1.6 release in July 2024 is the substantive one: combine_supp() learned to handle zero-row supplemental data, to refuse QNAM columns already present in the source, and to route multiple QNAM values to the same IDVAR, alongside enhanced controlled-terminology checks and record-uniqueness verification. Nothing has shipped since.

◆ Where it's heading

The package's development has been concentrated on one function, combine_supp(), which is where the messy realities of supplemental qualifiers surface — whitespace in join keys, empty supp datasets, colliding names. 0.1.6 also drew three first-time contributors, which is the healthiest signal in the history, but no release has followed. Sibling packages have meanwhile been dropping metatools as a dependency.

◆ Prediction

Without a release in two years the package looks stable rather than active; the plausible trigger is a controlled-terminology or dplyr change that forces the checks to be updated.
