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超文本标记语言（HyperText Markup Language，HTML）内容作为R绘图的一部分进行渲染的R包。其中核心包名为layoutEngine，但该包需依赖一款用于执行HTML布局计算的后端包。本次演示了三款示例后端包，分别为layoutEngineCSSBox、layoutEnginePhantomJS与layoutEngineDOM。此外，本报告还介绍了两款全新的字体包：gyre与courier。
