RMarkdown中的多线方程 [英] multi-line equation in RMarkdown

问题描述

我正在尝试在RMarkdown中创建多线方程.我已尝试从 http://www.rstudio.com/ide/提取的以下代码docs/authoring/using_markdown_equations ，

I am trying to create a multi-line equation in RMarkdown. I have tried the following code, extracted from http://www.rstudio.com/ide/docs/authoring/using_markdown_equations,

$$
\begin{aligned}
  \dot{x} & = \sigma(y-x) \\
  \dot{y} & = \rho x- y - xz 
\end{aligned}
$$

但是，经过编织的HTML文档给出了单行公式:

however the knitred HTML document gives a single-line equation:

推荐答案

当使用knitr剪切并粘贴到Windows 7中的RStudio中时，此代码可根据需要生成2条HTML行.如果删除了第三行末尾的第二个斜杠，则会产生示例中所示的结果.

This code produced 2 HTML lines, as desired, when cut and paste into RStudio in Windows 7 with knitr. If the second slash at the end of the 3rd line was removed, it produced the result shown in example.
