Changelog

gander (development version)

  • Introduced gander.chat, gander.style, and gander.dims as the preferred option names, following standard R package option naming conventions. The legacy options .gander_chat, .gander_style, and .gander_dims continue to work and will not be deprecated.

  • Updated recommended models to Claude Sonnet 4.6, GPT-4.1, and Gemini 3 Flash.

  • Rewrote prompt structure to more clearly communicate the agent’s task. This should broadly result in stronger understanding of user requests and stronger adherence to system instructions (#67).

  • Improved performance in Quarto documents (#30).

gander 0.1.0

CRAN release: 2025-02-19

  • Initial CRAN submission.

Notable changes pre-CRAN submission

Early adopters of the package will note two changes made shortly before the release of the package to CRAN:

  • The configuration options .gander_fn and .gander_args have been transitioned to one option, .gander_chat. That option takes an ellmer Chat, e.g.  options(.gander_chat = ellmer::chat_anthropic()). If you’ve configured an ellmer model using the previous options, you’ll get an error that automatically translates to the new code you need to use.

  • There is no longer a default ellmer model. Early in the development of gander, if you had an ANTHROPIC_API_KEY set up, the addin would “just work.” While this was convenient for Claude users, it means that the package spends money on the users behalf without any explicit opt-in.
