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.

Exploring and Testing the Toolchain and System Libraries

Helper functions that interface with the system utilities to learn about the local build environment. Lets you explore 'make' rules to test the local configuration, or query 'pkg-config' to find compiler flags and libs needed for building packages with external dependencies. Also contains tools to analyze which libraries that a installed R package linked to by inspecting output from 'ldd' in combination with information from your distribution package manager, e.g. 'rpm' or 'dpkg'.

A Clean, Whitespace-Sensitive Template Language for Writing HTML

Jade is a high performance template engine heavily influenced by Haml and implemented with JavaScript for node and browsers.

HTTP and WebSocket Server Library

Provides low-level socket and protocol support for handling HTTP and WebSocket requests directly from within R. It is primarily intended as a building block for other packages, rather than making it particularly easy to create complete web applications using httpuv alone. httpuv is built on top of the libuv and http-parser C libraries, both of which were developed by Joyent, Inc. (See LICENSE file for libuv and http-parser license information.)

Utilities for Graphical Rendering and Fonts Management

Tools are provided to compute metrics of formatted strings and to check the availability of a font. Another set of functions is provided to support the collection of fonts from 'Google Fonts' in a cache. Their use is simple within 'R Markdown' documents and 'shiny' applications but also with graphic productions generated with the 'ggiraph', 'ragg' and 'svglite' packages or with tabular productions from the 'flextable' package.

Extract Text from Rich Text Format (RTF) Documents

Wraps the 'unrtf' utility < https://www.gnu.org/software/unrtf/> 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.

Authenticate as a 'GitHub' App

'GitHub' apps provide a powerful way to manage fine grained programmatic access to specific 'git' repositories, without having to create dummy users, and which are safer than a personal access token for automated tasks. This package extends the 'gh' package to let you authenticate and interact with 'GitHub' < https://docs.github.com/en/rest/overview> in 'R' as an app.

Working with Audio and Video in R

Bindings to 'FFmpeg' < http://www.ffmpeg.org/> AV library for working with audio and video in R. Generates high quality video from images or R graphics with custom audio. Also offers high performance tools for reading raw audio, creating 'spectrograms', and converting between countless audio / video formats. This package interfaces directly to the C API and does not require any command line utilities.

Open Source OCR Engine

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.
