%description
Enables Retrieval-Augmented Generation (RAG) workflows in R by combining
local vector search using 'DuckDB' with optional web search via the
'Tavily' API. Supports OpenAI- and Ollama-compatible embedding models,
full-text and HNSW (Hierarchical Navigable Small World) indexing, and
modular large language model (LLM) invocation. Designed for advanced
question-answering, chat-based applications, and production-ready AI
pipelines. This package is the R equivalent of the 'python' package
'RAGFlowChain' available at <https://pypi.org/project/RAGFlowChain/>.
