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.

'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.

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.

Server-Side Syntax Highlighting

Prism < https://prismjs.com/> is a lightweight, extensible syntax highlighter, built with modern web standards in mind. This package provides server-side rendering in R using 'V8' such that no JavaScript library is required in the resulting HTML documents. Over 400 languages are supported.

A GraphQL Query Parser

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

Fast and Simple Badge Generator

Bindings to 'badgen' < https://www.npmjs.com/package/badgen> to generate beautiful 'svg' badges in R without internet access. Images can be converted to 'png' using the 'rsvg' package as shown in examples.

Bindings to AppArmor and Security Related Linux Tools

Bindings to kernel methods for enforcing security restrictions. AppArmor can apply mandatory access control (MAC) policies on a given task (process) via security profiles with detailed ACL definitions. In addition this package implements bindings for setting process resource limits (rlimit), uid, gid, affinity and priority. The high level R function 'eval.secure' builds on these methods to perform dynamic sandboxing: it evaluates a single R expression within a temporary fork which acts as a sandbox by enforcing fine grained restrictions without affecting the main R process. A portable version of this function is now available in the 'unix' package.

POSIX System Utilities

Bindings to system utilities found in most Unix systems such as POSIX functions which are not part of the Standard C Library.

Utility Functions for Developing Web Applications

Parses http request data in application/json, multipart/form-data, or application/x-www-form-urlencoded format. Includes example of hosting and parsing html form data in R using either 'httpuv' or 'Rhttpd'.
