imf.data - An Interface to IMF (International Monetary Fund) Data

Provides low-level access to the International Monetary Fund Statistical Data and Metadata eXchange ('SDMX') 3.0 API, available at <https://data.imf.org/>, and a concise workflow for discovering datasets, inspecting dimensions, and downloading observations as tidy data frames.

decimal - Exact Arbitrary-Precision Decimal Vectors

Arbitrary-precision vectors with an exact decimal representation, avoiding the rounding surprises of binary floating point. Built on the 'mpdecimal' C library, arithmetic is governed by an explicit decimal context controlling precision, rounding, and signaling, and vectors integrate with 'vctrs' for use in data frames, 'tibble' objects, summaries, and common numeric workflows. Missing values, signed zeros, infinities, and not-a-number values are supported throughout. The arithmetic model follows Cowlishaw (2009) "General Decimal Arithmetic" <https://speleotrove.com/decimal/decarith.html>.

zuhtml - Parse 'HTML' with a Bundled 'Gumbo' Parser

Parses real-world 'HTML' with a bundled copy of the 'Gumbo' parser (<https://codeberg.org/gumbo-parser/gumbo-parser>), which follows the 'WHATWG' parsing algorithm, so that no system library is required. Documents become immutable trees navigated with a documented subset of 'CSS' selectors. Attributes, text, lists, tables, links, forms and page metadata ('JSON-LD', microdata) are extracted into ordinary character vectors, lists and data frames, and nodes convert to 'Markdown'. Input is a string, raw bytes, a file, a URL or a connection, and raw input is decoded as browsers decode it, from a byte-order mark or a '<meta>' declaration. Parsing is bounded by limits on input size, native memory and nesting depth.

openlineage - Create and Emit 'OpenLineage' Events

Construct and validate run events that follow the 'OpenLineage' specification <https://openlineage.io/>. Model run lifecycles, datasets, and extensible facets with protocol-aware 'R' objects. Serialize events into deterministic JavaScript Object Notation (JSON) while preserving wire field names. Deliver events synchronously over Hypertext Transfer Protocol (HTTP) with authentication and retries, or use offline transports for local development and testing.

azr - Credential Chain for Seamless 'OAuth 2.0' Authentication to 'Azure Services'

Implements a credential chain for 'Azure OAuth 2.0' authentication based on the package 'httr2''s 'OAuth' framework. Sequentially attempts authentication methods until one succeeds. During development allows interactive browser-based flows ('Device Code' and 'Auth Code' flows) and non-interactive flow ('Client Secret') in batch mode.

qio - Read and Write 'Apache Parquet' Files

Read and write 'Apache Parquet' files. Whole files are read with a single call, and larger ones can be opened to inspect their schema and read selected columns, row groups, or batches. Built on the bundled C library 'carquet', with no required R package dependencies.

mdbx - Bindings to the 'libmdbx' Embedded Key-Value Store

Provides low-level bindings to 'libmdbx', a compact and fast transactional key-value store built on memory-mapped files (<https://libmdbx.dqdkfa.ru/>). Database environments, transactions, and byte-oriented read and write operations are exposed directly. The 'libmdbx' sources are bundled and compiled into the package, so no system library installation is required.

data.sketches - Probabilistic Streaming Data Sketches

Provides an interface to the 'Apache DataSketches' (<https://datasketches.apache.org/>) library of streaming algorithms for approximate analytics on data too large to hold or process exactly. Sketches are compact, mergeable summaries built in a single pass over a stream that answer queries such as approximate distinct counts, quantiles and ranks, frequent items and point-frequency estimates, weighted sampling, and set membership with mathematically proven error bounds. Implements Karnin-Lang-Liberty (KLL), Relative Error Quantiles (REQ), t-Digest, HyperLogLog (HLL), Compressed Probabilistic Counting (CPC), Theta, Frequent Items, Count-Min, Array of Doubles, Variance Optimal (VarOpt), Exact and Bounded Probabilistic Proportional-to-Size (EBPPS), and Bloom filter sketches, with native serialization for interoperability with other 'Apache DataSketches' implementations.

agecrypt - File Encryption with the 'age' Format

An idiomatic R interface to the 'age' file encryption format (<https://age-encryption.org/v1>), backed by a vendored copy of the 'agec' C implementation (<https://git.sr.ht/~min/agec>). Encrypt and decrypt raw vectors, files, and strings for one or more X25519 recipients or with a passphrase, with optional ASCII armor. Cryptography is vendored and randomness is drawn from the operating system, so the package has no external library dependencies.

zujson - Lightweight JSON Parsing and Serialization

Converts between JSON text and ordinary R vectors and lists through a small, predictable set of functions, backed by vendored 'yyjson' <https://github.com/ibireme/yyjson> and requiring no system JSON library. Parsing accepts character, raw and file input and reports failures through structured conditions; serialization writes UTF-8 bytes suitable for use directly as an HTTP request body. The type mapping is deliberately narrow and fully documented, so what goes in and what comes out are both predictable.

quak - Query 'Azure Data Lake Storage Gen2' with 'DuckDB'

Provides convenience utilities for using 'DuckDB' directly over datasets stored in 'Azure Data Lake Storage Gen2' (ADLS Gen2, 'abfss://'). Opens connections configured for Azure-backed 'Delta Lake' and 'Parquet' data, registers Azure credentials as 'DuckDB' secrets, and supports optional repository mirrors for restricted networks. Integrates well with 'DBI' for SQL workflows and with 'dplyr' and 'dbplyr' for lazy table queries.

zuyaml - Parse and Emit 'YAML' 1.2

Converts between 'YAML' 1.2 (<https://yaml.org/spec/1.2.2/>) and ordinary R objects using a bundled copy of the 'cyaml' C11 parser and emitter (<https://github.com/andrewmd5/cyaml>), so there is no system dependency and no runtime dependency beyond R itself. Ambiguous 'YAML' features are handled strictly and predictably: duplicate keys are refused by default, the 'YAML' 1.2 core schema is followed so that yes and no resolve as strings, and integers beyond double precision are preserved rather than silently rounded. A stream of documents and a sequence are different things, and the interface keeps them apart. Input size, nesting depth and the number of values materialised are all bounded, which makes the parser usable on untrusted input.
