What is nametagger?

An R binding to NameTag that has not gained a feature since its 2020 debut.

nametagger wraps UFAL's NameTag for named entity recognition in R, letting users apply and train NER models on tokenized text. Every release after the initial 0.1.0 is compiler or CRAN conformance work: misaligned-address and UBSan reports, a C++20 declaration fix for persistent_unordered_map, dropping C++11, and a sprintf swap. The R-level API has not moved.

What is ragnar?

ragnar turned its RAG store into an MCP server, so coding agents can search it directly.

ragnar builds retrieval-augmented generation stores in R on DuckDB, handling document chunking, embedding, and hybrid vector plus BM25 retrieval, and registering itself as a tool for ellmer chats. Version 0.3.0 adds mcp_serve_store(), which exposes a store over MCP to local clients such as Codex CLI and Claude Code, alongside Azure AI Foundry and Snowflake Cortex embedding providers. Store version 2, introduced in 0.2.0, brought chunk deoverlapping on retrieval and automatic heading augmentation.

An R binding to NameTag that has not gained a feature since its 2020 debut.

◆ Current state

nametagger wraps UFAL's NameTag for named entity recognition in R, letting users apply and train NER models on tokenized text. Every release after the initial 0.1.0 is compiler or CRAN conformance work: misaligned-address and UBSan reports, a C++20 declaration fix for persistent_unordered_map, dropping C++11, and a sprintf swap. The R-level API has not moved.

◆ Where it's heading

The package is maintained as part of a family of bnosac NLP bindings that are updated together — the same C++20 persistent_unordered_map fix appears in udpipe within days, and the C++11 drops across the family landed in the same sweep. Releases are triggered by CRAN's checks, not by NameTag's own development.

◆ Prediction

Expect the next release to be whichever compiler conformance issue CRAN raises next, most likely arriving alongside matching fixes in the sibling packages.

ragnar turned its RAG store into an MCP server, so coding agents can search it directly.

◆ Current state

ragnar builds retrieval-augmented generation stores in R on DuckDB, handling document chunking, embedding, and hybrid vector plus BM25 retrieval, and registering itself as a tool for ellmer chats. Version 0.3.0 adds mcp_serve_store(), which exposes a store over MCP to local clients such as Codex CLI and Claude Code, alongside Azure AI Foundry and Snowflake Cortex embedding providers. Store version 2, introduced in 0.2.0, brought chunk deoverlapping on retrieval and automatic heading augmentation.

◆ Where it's heading

The package keeps widening who can reach a store and how many ways they can query it. Retrieval accepts vectors of queries, the ellmer tool withholds chunks it has already returned so an agent can dig deeper across calls, and now the store is reachable from outside R entirely. Embedding providers are added steadily — LM Studio, then Azure and Snowflake — which keeps the store portable across whoever supplies the vectors. Breaking changes are accepted readily at this stage, including a renamed default tool prefix and a flipped default in ragnar_find_links().

◆ Prediction

More MCP surface is the natural next step now that serving exists, since the retrieval tool already has the multi-query and no-repeat behavior that agent-driven search depends on.
