🇷🤝💬 R-help-chat
Search and chat with the R-help and R-devel mailing list archives. An LLM turns your question into a search query, including year ranges and months. Retrieved emails are shown below the chatbot and are used by the LLM to generate an answer. You can ask follow-up questions with the chat history as context; changing the mailing list maintains history. Press the clear button (🗑) to clear the history and start a new chat.
