Provenance Collector

Defines functions that can be used to collect provenance as an 'R' script executes or during a console session. The output is a text file in 'PROV-JSON' format.

Validate Brazilian Administrative Registers - Valida Documentos

Contains functions to validate administrative register as CPF (Cadastro de Pessoa Fisica), CNPJ (Cadastro de Pessoa Juridica), PIS (Programa de Integracao Social), CNES (Cadastro Nacional de Saude). Builds from and improves on previous package from IPEA validaRA < https://github.com/ipea/validaRA>. It can check individual registers or help creating a table summarizing validity of a set.

Compare Provenance Collections to Explain Changed Script Outputs

Inspects provenance collected by the 'rdt' or 'rdtLite' packages, or other tools providing compatible PROV JSON output created by the execution of a script, and find differences between two provenance collections. Factors under examination included the hardware and software used to execute the script, versions of attached libraries, use of global variables, modified inputs and outputs, and changes in main and sourced scripts. Based on detected changes, 'provExplainR' can be used to study how these factors affect the behavior of the script and generate a promising diagnosis of the causes of different script results. More information about 'rdtLite' and associated tools is available at < https://github.com/End-to-end-provenance/> and Barbara Lerner, Emery Boose, and Luis Perez (2018), Using Introspection to Collect Provenance in R, Informatics, .

Epimed Solutions Collection for Data Editing, Analysis, and Benchmark of Health Units

Collection of functions related to benchmark with prediction models for data analysis and editing of clinical and epidemiological data.

Acquisition and Reading of Brazilian Federal Government Fund Transfers

Downloads, reads and organizes data on federal fund transfers to Brazilian municipalities. Data are retrieved from the TransfereGov "Fundo a Fundo" API, from the Portal da Transparência open data service and from the Tesouro Transparente CKAN catalogue. The package offers one reader per API endpoint, helpers that map SIAFI municipality codes to IBGE codes, and routines that fetch the monthly transfer archives and the tax waiver records published as open data.

Threshold-Free Class-Specific Comparison of Binary Classifiers

Implements the U-smile methodology for threshold-free, class-specific comparison of probabilistic binary classifiers. The package quantifies prediction improvement and worsening separately for non-events and events using the Brier alteration (BA), relative Brier (RB), improvement proportion (I) coefficients, and relative likelihood ratio (rLR) coefficients, and provides U-smile, prediction improvement-worsening, receiver operating characteristic, and precision-recall plots. The original U-smile framework is described in Kubiak et al. (2024) , its three-level extension for imbalanced binary classification in Wieckowska et al. (2025) , and the likelihood-based extension in Wieckowska and Guzik (2026) .

Translate 'LaTeX' Formulas to R Code

Implements a minimal 'LaTeX' parser that translates mathematical formulas into R code strings. Supports arithmetic operators, implicit multiplication, fractions, Greek letters, common mathematical functions, and statistical notation for means, medians, and rolling sums. Input from visual formula editors such as 'MathQuill' is normalized automatically, and the resulting string can be evaluated with parse() and eval(), or converted into an R function with latex2fun(). The implementation follows the tree-walking interpreter design of Nystrom (2021) < https://craftinginterpreters.com/>.

Structural Equation Modeling with Deep Neural Network and Machine Learning Algorithms

Training and validation of a custom (or data-driven) Structural Equation Models using Deep Neural Networks or Machine Learning algorithms, which extend the fitting procedures of the 'SEMgraph' R package .

Record Linkage Functions for Linking and Deduplicating Data Sets

Provides functions for linking and deduplicating data sets. Methods based on a stochastic approach are implemented as well as classification algorithms from the machine learning domain. For details, see our paper "The RecordLinkage Package: Detecting Errors in Data" Sariyar M / Borg A (2010) .
