Rendering HTML Content in R Graphics

This report describes several R packages that allow HTML content to be rendered as part of an R plot. The core package is called 'layoutEngine', but that package requires a "backend" package to perform HTML layout calculations. Three example backends are demonstrated: 'layoutEngineCSSBox', 'layoutEnginePhantomJS', and 'layoutEngineDOM'. We also introduce two new font packages, 'gyre' and 'courier'.

本报告介绍了多款可将HTML内容作为R绘图的一部分进行渲染的R扩展包。核心扩展包名为'layoutEngine'，但该扩展包需要依托一款“后端”扩展包来完成HTML布局计算。本次演示了三款示例后端扩展包：'layoutEngineCSSBox'、'layoutEnginePhantomJS'与'layoutEngineDOM'。此外，本报告还介绍了两款全新的字体扩展包：'gyre'与'courier'。
