A\nsingle function, peter(), opens an interactive chat in the\nconsole or, given a prompt, runs the agent loop and returns a\nvalue that can be piped into further prompts. Supports the\n'Anthropic', 'OpenAI' and 'Google Gemini' application\nprogramming interfaces, 'OpenAI'-compatible endpoints, the\n'Claude Code' and 'Codex' command line tools, local 'Ollama'\nconversational models, and System One typed-decision models\nsuch as 'Jev', 'Clef' and 'Clef Flash'\n,\nwhose typed yes/no, choice and score answers can be used\ndirectly in if() and for() statements. Tools for reading,\nwriting, editing and searching files and for evaluating 'R'\ncode are implemented in 'R'; skills, extensions, Model Context\nProtocol ('MCP') servers, sub-agents and 'shiny' apps are\nsupported. Sessions are recorded as 'R' scripts, 'R Markdown',\n'Quarto' or 'Jupyter' documents that can be re-run.
