一致的代码html内联并与knitr成块 [英] consistent code html inline and in chunks with knitr
本文介绍了一致的代码html内联并与knitr成块的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我希望段落中的代码与代码块中显示的代码一致.
I would like the code in paragraphs to be consistent with the code shown in code chunks.
例如:
<p>
The formula method for a linear model
is <code>lm(y~x, data = dat)</code>.
For our data the results are:
</p>
<!--begin.rcode
lm(y~x, data = dat)
end.rcode-->
最好内联使用<code>以外的东西，并获得与块代码相同的格式.
It would be nice to use something besides <code> inline and get the same formatting as the chunk's code.
我正在使用knitr:
> sessionInfo()
R version 3.0.1 (2013-05-16)
Platform: x86_64-apple-darwin10.8.0 (64-bit)
locale:
[1] en_US.UTF-8/en_US.UTF-8/en_US.UTF-8/C/en_US.UTF-8/en_US.UTF-8
attached base packages:
[1] stats graphics grDevices utils datasets
[6] methods base
other attached packages:
[1] knitr_1.2
loaded via a namespace (and not attached):
[1] digest_0.6.3 evaluate_0.4.3 formatR_0.7
[4] stringr_0.6.2 tools_3.0.1
谢谢

推荐答案
您可以重新定义inline挂钩，并将内联代码编写为字符串.下面是一个最小的示例(请确保您使用的是所有R包的最新版本):
You can redefine the inline hook, and write your inline code as character strings. Below is a minimal example (make sure you are using the latest versions of all R packages):
<!DOCTYPE html>
<html>
<head>
<title>Highlight inline R code</title>
</head>
<body>
<!--begin.rcode
library(knitr)
hook_inline = knit_hooks$get('inline')
knit_hooks$set(inline = function(x) {
if (is.character(x)) highr::hi_html(x) else hook_inline(x)
})
end.rcode-->
<p>
The formula method for a linear model
is <code><!--rinline 'lm(y~x, data = dat)' --></code>.
For our data the results are:
</p>
<!--begin.rcode eval=FALSE
lm(y~x, data = dat)
end.rcode-->
</body>
</html>
关键是要通过highr::hi_html()突出显示语法，这是输出:
The key is to do syntax highlighting via highr::hi_html(), and here is the output:
