ellmer is the hub of the R AI stack. Provides unified interface to 20+ LLM providers (OpenAI, Claude, Ollama, etc.) with stateful chat sessions, tool calling, and token tracking.
Install: install.packages("ellmer")
API keys: Set OPENAI_API_KEY or ANTHROPIC_API_KEY in .Renviron
Read references/API.md before writing code.
references/API.md - Complete function referencereferences/getting-started.md - Core workflow and chat patternsreferences/tool-calling.md - Tool registration and function calling# Create chat
chat <- chat_openai(model = "gpt-4o")
chat <- chat_claude(model = "claude-sonnet-4")
chat <- chat_ollama(model = "llama3.2") # Local
# Chat (stateful - history preserved)
chat$chat("Explain this error")
chat$chat("How do I fix it?") # Remembers context
# Fresh conversation
chat <- chat_openai() # New = no history
# Track costs
token_usage()
# Tool calling
chat$set_tools(btw_tools()) # See r-btw skill
| Issue | Solution |
|---|---|
| Forgot API key | Set in .Renviron, restart R |
| Ollama connection error | Run ollama serve first |
| Conversation too long/expensive | Start fresh chat for new topics |
| Expecting accuracy | LLMs for prototyping, not critical work |
| Using chat for single request | Just use httr2 for one-off calls |
Custom chatbots: Preload with documentation, package info, educational materials
Structured data extraction: Sentiment analysis, geocoding, recipe parsing, document indexing
Programming assistance: Code modernization, documentation lookup, explanation, security analysis
Other: Alt text generation, statistical reasoning, brand style guide enforcement

Use when code loads or uses duckspatial (library(duckspatial), duckspatial::), performing spatial joins or areal interpolation on large vector datasets in R, or needing faster spatial operations than sf
Use when creating, editing, or validating R package skills (library(pkg), pkg::), or gathering R package documentation (CRAN, pkgdown, vignettes) to generate a skill
Use when code loads or uses btw (library(btw), btw::), providing R session context to LLMs, registering tools for ellmer chat, or copying R object descriptions to clipboard
