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.

Extensible Style-Sheet Language Transformations

An extension for the 'xml2' package to transform XML documents by applying an 'xslt' style-sheet.

'Blowfish' Password Hashing Algorithm

Bindings to the 'blowfish' password hashing algorithm derived from the 'OpenBSD' implementation.

Utilities for Graphical Rendering

Useful tools for writing vector graphics devices.

A Compression Format Optimized for the Web

A lossless compressed data format that uses a combination of the LZ77 algorithm and Huffman coding. Brotli is similar in speed to deflate (gzip) but offers more dense compression.

Client for 'jq', a 'JSON' Processor

Client for 'jq', a 'JSON' processor (< https://stedolan.github.io/jq/>), written in C. 'jq' allows the following with 'JSON' data: index into, parse, do calculations, cut up and filter, change key names and values, perform conditionals and comparisons, and more.

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.

Bindings to 'OpenCV' Computer Vision Library

Experimenting with computer vision and machine learning in R. This package exposes some of the available 'OpenCV' vision algorithms, such as edge, body or face detection. These can either be applied to analyze static images, or to filter live video footage from a camera device.

R Bindings for 'ZeroMQ'

Interface to the 'ZeroMQ' lightweight messaging kernel (see < http://www.zeromq.org/> for more information).

Extract Text from Rich Text Format (RTF) Documents

Wraps the 'unrtf' utility to extract text from RTF files. Supports document conversion to HTML, LaTeX or plain text. Output in HTML is recommended because 'unrtf' has limited support for converting between character encodings.
