[英]Subscript spacing using knitr and RStudio Markdown
I've created and RMarkdown file in RStudio. 我已经在RStudio中创建了RMarkdown文件。 I've inserted this code in my RMarkdown file. 我已将此代码插入RMarkdown文件中。
$$\begin{align*}
\sum_{k=1}^n c x_k
&=cx_1+cx_2+\cdots+cx_n\\
&=c(x_1+x_2+\cdots+x_n)\\
&=c\sum_{k=1}^nx_k
\end{align*}$$
Compiling with knitHTML, I get the following image. 使用knitHTML进行编译,我得到以下图像。
Note how the subscript k is crammed too tightly against x. 请注意,下标k如何相对于x太紧塞。 Of course, I can try: 当然,我可以尝试:
c x_{\\,k} c x _ {\\,k}
but then it is a bit too far. 但这有点太过分了。 I am wondering why the code x_k doesn't work the spacing as it does normally in latex. 我想知道为什么代码x_k不能像乳胶中那样正常工作。
Any suggestions? 有什么建议么?

PS For those wanting the RMarkdown source and resulting html file: PS对于那些想要RMarkdown源和生成的html文件的人:
It's quite easy. 这很容易。 Take H2O for example. 以水为例。 Implement the following code: H~2~o
执行以下代码: H~2~o
