如何使用Knitr和Pandoc在Rmarkdown中包含DT数据表的js依赖项 [英] Howto include js dependencies of DT datatable in Rmarkdown using knitr and pandoc
问题描述
有没有一种方法可以用DT在RStudio之外生成的数据表来编译RMarkdown文档？
Is there a way to compile RMarkdown documents with datatables produced by DT outside of RStudio?
我试图在我的RMarkdown文档中包括一个数据表小部件然后要使用knitr和pandoc转换为html。这在RStudio上可以正常使用，但是如果我尝试对knitr和pandoc进行相同操作，则无法获取有效的html文件。
I'm trying to include a datatable widget in an RMarkdown document that I then want to convert to html using knitr and pandoc. This works fine with RStudio but if I try to do the same with knitr and pandoc I'm unable to get a working html file.
这里是一个最小的示例可以与RStudio一起使用的Rmd文件，但不适用于其他版本：
Here is a minimal example of an Rmd file that works with RStudio but not otherwise:
---
title: "Minimal DT example"
---
<style type="text/css"> table, table th, table td { border: none; } </style>
```{r}
library(DT)
datatable(iris)
```
然后我想使用以下方式转换为html：
Which I would then like to convert to html using:
knitr::knit('example.Rmd')
knitr::pandoc('example.md',format="html")
我知道RStudio使用了更为复杂的pandoc调用：
I am aware that RStudio uses a much more complicated pandoc call:
/usr/lib/rstudio/bin/pandoc/pandoc scratch.utf8.md --to html --from markdown+autolink_bare_uris+ascii_identifiers+tex_math_single_backslash-implicit_figures --output scratch.html --smart --email-obfuscation none --self-contained --standalone --section-divs --template /home/user/R/x86_64-pc-linux-gnu-library/3.1/rmarkdown/rmd/h/default.html --variable 'theme:bootstrap' --include-in-header /tmp/RtmpMLtVfF/rmarkdown-str24935297671d.html --mathjax --variable 'mathjax-url:https://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML' --no-highlight --variable highlightjs=/home/user/R/x86_64-pc-linux-gnu-library/3.1/rmarkdown/rmd/h/highlight
我可以重新创建该部分该tmp文件包含在标头中的位置：
which I can recreate up to the part where this tmp file is included in the header:
/tmp/RtmpMLtVfF/rmarkdown-str24935297671d.html
我假定此文件包含jquery和datatables的js源。我试图从软件包源中手动添加它们-但没有成功-并且无论如何都希望有一种开箱即用的解决方案。
I assume that this file contains the js sources for jquery and datatables. I have tried to add them by hand from the package source - but not succeeded - and would anyways like a solution that works out of the box.
推荐答案
RStudio正在使用的软件包为 rmarkdown 。它处理Knit命令，并将工作委托给knitr和pandoc，还负责捆绑依赖项并将它们注入到文档中。
The package RStudio is using under the hood is rmarkdown. It handles the Knit command and delegates work to knitr and pandoc, and it's also responsible for bundling dependencies and injecting them into the doc.
您可能已经安装了该软件包，因此您应该能够一次生成HTML文件：
You likely already have the package installed, so you should be able to do this to produce your HTML file in one go:
rmarkdown::render('example.Rmd')
