RAGFlowChainR 0.1.6 (2026-02-14)

CRAN release: 2026-02-22

  • Added four new retrieval backends in create_rag_chain():
    • Qdrant
    • Pinecone
    • Weaviate
    • Elasticsearch
  • Expanded backend routing and parsing in create_rag_chain() / perform_web_search() to support:
    • Local backends: DuckDB, VectrixDB
    • Remote backends: Qdrant, Pinecone, Weaviate, Elasticsearch
  • Added backend adapter tests for all new methods and kept existing DuckDB/VectrixDB coverage.
  • Added backend-focused vignettes:
    • duckdb-backend.Rmd
    • vectrixdb-backend.Rmd
    • qdrant-backend.Rmd
    • pinecone-backend.Rmd
    • weaviate-backend.Rmd
    • elasticsearch-backend.Rmd
  • Updated _pkgdown.yml backend articles grouping:
    • Requires Embedding ML
    • Doesnt Require Embedding ML
  • CI/workflow improvements:
    • Added .github/workflows/R-CMD-check.yaml
    • Added .github/workflows/rmd-check.yaml
    • Updated pkgdown.yaml to run on main and deploy with clean pages output.
  • README updates:
    • Streamlined README content and moved detailed backend walkthroughs to vignettes.
    • Added backend guide links for faster navigation.
  • Wrapped FTS-related tests in tryCatch() + skip() to avoid segmentation faults on Fedora-clang during CRAN checks.
  • Informative skip() messages added for systems without FTS extension support.
  • Ensured all tests pass cleanly on platforms with partial DuckDB extension support.
  • Maintained full feature test coverage in interactive/development environments.

RAGFlowChainR 0.1.1

CRAN release: 2025-04-24

  • Prevented segfaults on CRAN by disabling the experimental vss extension during checks.

  • Fallback to FLOAT[] column type when vss is unavailable, avoiding Fedora-clang binary-extension errors.

  • create_vectorstore() now:

    • Skips vss installation/loading under CRAN but retains support in dev environments.
    • Returns a persistent DuckDB connection (no longer auto-disconnects).

  • insert_vectors():

    • Handles single-column frames safely using drop = FALSE.
    • Dynamically switches between array_value() and list_value() based on schema.

  • build_vector_index():

    • Skips HNSW index creation when VECTOR[] columns are missing (with a warning).

  • RAG chain integration:

  • DESCRIPTION and metadata:

    • Set minimum required version: duckdb (>= 0.10.0) and testthat (>= 3.0.0).
    • Added Config/testthat/edition: 3 for consistent test behavior.
    • Tidied Description field by removing unnecessary single quotes around names.
    • Expanded common acronyms like HNSW, LLM, etc.

  • Testing improvements:

    • Suppressed non-critical test warnings.
    • Removed fragile FTS assertions (fts_main).
    • Introduced mock_embed() and dummy_embed() to remove dependency on external APIs.
    • Skipped RAG-chain integration tests on CRAN and gated test-data downloads.
