Open Source Software and Open Data

International Trade

• Tradestatistics: Open trade Statistics API wrapper and utility program.
• Wbstats: An R package for searching and downloading data from the World Bank API

Econometrics

• Capybara: Efficient Fixed-Effects Estimation in R With C++ 11 Backend.
• Gravity: Estimation methods for gravity models.
• Tradepolicy: Replication of an advanced guide to trade policy analysis.

R and C++ bindings

• Cpp4r: A collection of C++ bindings for R that defaults to C++11 and uses newer C++ features if those are supported.

Linear algebra

• Armadillo4r: Provides function declarations and inline function definitions that facilitate communication between R and the Armadillo C++ library for linear algebra and scientific computing. Significantly expands cpp11armadillo by providing support for complex numbers and uses C++11 (and newer) features if available.
• Cpp11armadillo: Provides function declarations and inline function definitions that facilitate communication between R and the Armadillo C++ library for linear algebra and scientific computing.

Data visualization

• D3po: A set of opinionated templates for quick data visualization using D3.js and R. It is fully compatible with RMarkdown and Shiny, and it is available under the Apache 2.0 license for use in commercial and non-commercial projects.

REDATAM format

• Open REDATAM (C++/bash): Open Redatam is an open source software for extracting raw information from REDATAM databases. It was created to recover information of REDATAM databases for statistical analysis using standard tools such as SPSS, STATA, R, etc.
• Redatam for R: Read REDATAM binary data directly in R. This is similar to the Haven package for SPSS/Stata datasets but for REDATAM formats.
• Redatam for Python: Read REDATAM binary data directly in R. This is similar to the Haven package for SPSS/Stata datasets but for REDATAM formats.

Data validation

Pointblank: Data validation and organization of metadata for local and remote tables.

Working with PDFs

• TabulaPDF: R bindings to the Tabula Java library for PDF tables extraction.
• Cpp11tesseract: Bindings to Tesseract, a powerful optical character recognition (OCR) engine that supports over 100 languages. The engine is highly configurable in order to tune the detection algorithms and obtain the best possible results.
• Cpp11poppler: Bindings to Poppler, a tool for extracting text, fonts, attachments and metadata from a PDF file. It also supports high quality rendering of PDF documents into PNG, JPEG, TIFF format, or into raw bitmap vectors for posterior processing.
• Cpp11qpdf: Bindings to Qpdf, an open-source PDF rendering library that allows to conduct content-preserving transformations of PDF files such as split, combine, and compress PDF files.
