[英]How to knit HTML into PDF using R?
I would like to transform HTML into PDF using R我想使用 R 将 HTML 转换为 PDF
I have tried using cat and rmarkdown.我试过使用 cat 和 rmarkdown。
Below is an example from this answer , and my goal is to make it look the same as what it appears in the web下面是这个答案的一个例子,我的目标是让它看起来和它在网络上出现的一样
<p>You can use the <a href="http://stat.ethz.ch/R-manual/R-devel/library/base/html/order.html" rel="noreferrer"><code>order()</code></a> function directly without resorting to add-on tools -- see this simpler answer which uses a trick right from the top of the <code>example(order)</code> code:</p>
<pre><code>R> dd[with(dd, order(-z, b)), ]
b x y z
4 Low C 9 2
2 Med D 3 1
1 Hi A 8 1
3 Hi A 9 1
</code></pre>
<p><em>Edit some 2+ years later:</em> It was just asked how to do this by column index. The answer is to simply pass the desired sorting column(s) to the <code>order()</code> function:</p>
<pre><code>R> dd[order(-dd[,4], dd[,1]), ]
b x y z
4 Low C 9 2
2 Med D 3 1
1 Hi A 8 1
3 Hi A 9 1
R>
</code></pre>
<p>rather than using the name of the column (and <code>with()</code> for easier/more direct access).</p>
Maybe R -e "rmarkdown::render('input.Rmd',output_file='output.pdf')"
也许R -e "rmarkdown::render('input.Rmd',output_file='output.pdf')"
So assuming you have this in a Rmakrdown file:所以假设你在 Rmakrdown 文件中有这个:
---
title: "R Notebook"
output:
pdf_document: default
html_notebook: default
---
You can use the [`order()`](http://stat.ethz.ch/R-manual/R-devel/library/base/html/order.html) function directly without resorting to add-on tools -- see this simpler answer which uses a trick right from the top of the `example(order)` code:
```{r eval=FALSE}
R> dd[with(dd, order(-z, b)), ]
b x y z
4 Low C 9 2
2 Med D 3 1
1 Hi A 8 1
3 Hi A 9 1
_```
Knitting it will result in a pdf that looks like this:编织它会产生一个看起来像这样的pdf:
Similarly, if you don't want to create a rmd but use the html, you can do: R -e "rmarkdown::pandoc_convert('input.html', output = 'output.pdf')"
同样,如果您不想创建 rmd 而是使用 html,则可以执行以下操作: R -e "rmarkdown::pandoc_convert('input.html', output = 'output.pdf')"
Which will result in a pdf looking like this:这将导致 pdf 看起来像这样:
