We are happy to announce that ellmer 0.5.0 is now available on CRAN! ellmer is an R package that makes it easy to work with large language models directly from R. It supports a wide variety of providers (including OpenAI, Anthropic, Google, AWS Bedrock, Azure, Snowflake, Databricks, Posit, and many more), makes it easy to extract structured data, and lets the model call R functions via tool calling.
