Client for the 'AstraeaDB' Graph Database R package AstraeaDB version 0.2.1 Provides a client for 'AstraeaDB', a graph database with vector search capabilities. Supports node and edge create, read, update, and delete operations, label and edge-type lookups, graph traversals (breadth-first search, depth-first search, shortest path), temporal (time-travel) queries, graph algorithms (PageRank, Louvain community detection, connected components, and degree and betweenness centrality), vector similarity search, hybrid graph-vector search, Graph Query Language (GQL) execution, and graph-based retrieval-augmented generation (subgraph extraction with large language model integration). Communicates with the 'AstraeaDB' server over a JSON-over-TCP protocol. An optional 'Apache Arrow Flight' transport is available for high-performance bulk operations when the 'arrow' package is installed.
