Datamonger for R · r · 0.0.0.9000

Reference

• datamonger-package

  Reproducible Retrieval and Decoding of Public Research Data

  Datamonger retrieves public research datasets through immutable registry selectors, verifies exact artifact bytes, and verifies decoded logical values against a cross-language canonical digest. The package performs no telemetry.

• datamonger_cache_dir

  Select and Manage the Private R Cache

  Datamonger uses the cache returned by tools::R_user_dir() by default. An explicit path can select another persistent or temporary location. Eviction is manual, and active objects are skipped.

• dim.datamonger_csr_matrix

  Inspect a Sparse Matrix with Large Dimensions

  Datamonger normally returns sparse features as a row-compressed Matrix. When a declared dimension exceeds the Matrix integer limit, it returns a datamonger_csr_matrix that retains the exact dimensions and CSR arrays. These methods report its dimensions and a compact summary without allocating a dense matrix.

• fetch_data

  Retrieve or Inspect Registered Data

  Resolve a dataset within one strongly selected registry. Artifact size and SHA-256 verification cannot be disabled. Decoded verification is enabled by default and may be disabled only explicitly.

• format.datamonger_int64

  Display Exact 64-bit Integer Values

  Datamonger stores signed 64-bit integers as decimal character strings so that values outside R's exact numeric range retain all their digits. These methods display those strings without converting them to floating-point numbers.

• print.datamonger_registry

  Display Registry, Fetch, Dataset, and Cache Metadata

  Print compact summaries of Datamonger metadata objects. The methods read the object's fields without retrieving data or inspecting the cache again.

• registry_selector

  Select an Immutable Registry Release

  Construct, discover, set, or inspect a strong registry selector. A catalog lookup is TLS-trusted discovery; recording and reusing its returned release and digest creates the reproducible selector.
