Database Interface and MariaDB Driver

Implements a DBI-compliant interface to MariaDB (< https://mariadb.org/>) and MySQL (< https://www.mysql.com/>) databases.

Producing and Reproducing Results

A system for embedded scientific computing and reproducible research with R. The OpenCPU server exposes a simple but powerful HTTP api for RPC and data interchange with R. This provides a reliable and scalable foundation for statistical services or building R web applications. The OpenCPU server runs either as a single-user development server within the interactive R session, or as a multi-user Linux stack based on Apache2. The entire system is fully open source and permissively licensed. The OpenCPU website has detailed documentation and example apps.

Extract Text from Microsoft Word Documents

Wraps the 'AntiWord' utility to extract text from Microsoft Word documents. The utility only supports the old 'doc' format, not the new xml based 'docx' format. Use the 'xml2' package to read the latter.

Parsing and Evaluation Tools that Provide More Details than the Default

Parsing and evaluation tools that make it easy to recreate the command line behaviour of R.

'Blowfish' Key Derivation and Password Hashing

Bindings to the 'blowfish' password hashing algorithm < https://www.openbsd.org/papers/bcrypt-paper.pdf> derived from the 'OpenBSD' implementation.

Spherical Geometry Operators Using the S2 Geometry Library

Provides R bindings for Google's s2 library for geometric calculations on the sphere. High-performance constructors and exporters provide high compatibility with existing spatial packages, transformers construct new geometries from existing geometries, predicates provide a means to select geometries based on spatial relationships, and accessors extract information about geometries.

GNU Privacy Guard for R

Bindings to GnuPG for working with OpenGPG (RFC4880) cryptographic methods. Includes utilities for public key encryption, creating and verifying digital signatures, and managing your local keyring. Some functionality depends on the version of GnuPG that is installed on the system. On Windows this package can be used together with 'GPG4Win' which provides a GUI for managing keys and entering passphrases.

Bindings to 'OpenCV' Computer Vision Library

Exposes some of the available 'OpenCV' < https://opencv.org/> algorithms, such as a QR code scanner, and edge, body or face detection. These can either be applied to analyze static images, or to filter live video footage from a camera device.

Google's Compact Language Detector 3

Google's Compact Language Detector 3 is a neural network model for language identification and the successor of 'cld2' (available from CRAN). The algorithm is still experimental and takes a novel approach to language detection with different properties and outcomes. It can be useful to combine this with the Bayesian classifier results from 'cld2'. See < https://github.com/google/cld3#readme> for more information.

A GraphQL Query Parser

Bindings to the 'libgraphqlparser' C++ library. Parses GraphQL < https://graphql.org> syntax and exports the AST in JSON format.
