在没有RStudio的情况下将Rmarkdown转换为PDF [英] Converting Rmarkdown to PDF without RStudio

问题描述

我想将*.Rmd转换为PDF格式的文档 rstudio 可用.

当前方法

当前方法遵循以下步骤:

1. *.Rmd文档传递到knitr: knit(input = "report.Rmd"))

2. 通过pandoc转换获得的md:

   # Convert
   pandoc --smart --to latex \
          --latex-engine pdflatex \
          -s report.md \
          -o report.PDF
   

问题

这会导致以下问题，即 Rmarkdown 文档的顶部:

---
title:  "Report Title"
author: "Person"
output: pdf_document
classoption: landscape
---

并显示为:

所有文本都居中，而我希望将其左对齐:

可能的方法

我想使用 ;但是，尽管设置了RSTUDIO_PANDOC(如在此处所述)，该命令在pandoc不可用时仍会失败.

所需结果

我不太在乎所使用的机制是否利用了rmarkdown::render，我想要实现的是:

• 所有页面的横向页面布局
• 左对齐文本
• 通过控制默认字体对文档进行最小控制的能力

---

• 理想情况下，我希望在*.Rmd文件中尽可能多地执行操作，而无需在pandoc命令中添加参数.

更新，以下评论

• 我正在Linux上工作，并且已安装pandoc，我可以执行pandoc命令传递文件并毫无问题地生成导出文件.它只对rmarkdown::render包不起作用.
• 关于钩子和*.Rmd文件，这是我试图理解的内容，因为我发现我的*.Rmd文件的第一部分被忽略了.当前过程如下:
  • *.Rmd (其中不多，只是标题部分以及呈现但错误辩解的伪文本和代码)>
  • *.R 文件只运行一行knit(input = "report.Rmd")) >
  • *.sh 文件运行pandoc命令并生成PDF

有关:

如果一切就绪，那实际上只是对 rmarkdown::render(...)

rmarkdown::render(...)失败: Error: pandoc version 1.12.3 is required and was not found ... 但是:

>> rmarkdown::pandoc_available()
[1] TRUE

和:

$ pandoc -v
pandoc 1.9.4.1 (...)

RSTUDIO_PANDOC指向pandoc.

解决方案

几件事:

• 该命令在无法使用pandoc时失败." 很好，您必须安装了pandoc才能调用它-但您没有不要说您拥有什么操作系统.在Linux上，从软件包管理器安装pandoc非常简单.否则，jgm在网站上为您提供了二进制文件； 应该"在OS X上类似

• 对于不同的样式，您需要修改LaTeX代码，您可以通过大量的钩子来包含宏文件；有关详细信息，请参见RMarkdown备忘单

• 如果您想行使更多控制权，则可以提供自己的模板；我已经在 tint包中完成了此操作 (也位于CRAN上)

• 如果一切就绪，实际上只是对rmarkdown::render(...)
的调用

I would like to convert a *.Rmd to document to PDF without rstudio being available.

Current approach

Current approach follows the following steps:

1. *.Rmd document is passed to knitr: knit(input = "report.Rmd"))

2. Obtained md is converted via pandoc:

   # Convert
   pandoc --smart --to latex \
          --latex-engine pdflatex \
          -s report.md \
          -o report.PDF
   

Problems

This results in the following problems, the top section of the Rmarkdown document:

---
title:  "Report Title"
author: "Person"
output: pdf_document
classoption: landscape
---

and shows as:

all text is centered, whereas I would like for it to be left-aligned:

Possible approach

I would like to make use of the rmarkdown::render; however, despite setting RSTUDIO_PANDOC (as discussed here), the command fails on pandoc not being available.

Desired outcome

I don't care much whether the utilised mechanism makes use of the rmarkdown::render, what I want to achieve is:

• Landscape page layout across all pages
• Left-aligned text
• Ability to exercise minimum control over the document by controlling default fonts

---

• Ideally, I would like to do as much as in the *.Rmd file as possible without the need to add parameters to the pandoc command.

Updates, following comments

• I'm working on Linux and pandoc is installed, I can execute pandoc command pass files and generate exports with no problems. It only doesn't work with the rmarkdown::render package.
• Concerning the hooks and *.Rmd files, this is what I'm trying to understand as I see that that the first section of my *.Rmd file is ignored. The current process looks as follows:
  • *.Rmd (not much in it, just title section and dummy text and code that renders but wrongly justified) >
  • *.R file running one line knit(input = "report.Rmd")) >
  • *.sh file running pandoc command and generating PDF

Concerning:

if all that is in place, it is indeed just a call to rmarkdown::render(...)

The rmarkdown::render(...) fails: Error: pandoc version 1.12.3 is required and was not found ... However:

>> rmarkdown::pandoc_available()
[1] TRUE

and:

$ pandoc -v
pandoc 1.9.4.1 (...)

The RSTUDIO_PANDOC points to pandoc.

解决方案

A few things:

• "the command fails on pandoc not being available." well you must have pandoc installed in order to call it -- but you didn't say what OS you have. On Linux it is pretty trivial to install pandoc from the package manager; otherwise jgm has binaries for you on the site; "should" be similar on OS X

• for different styling you need to modify the LaTeX code which you can via numerous hooks to include macro files; see the RMarkdown cheat sheets for detail

• if you want to exercise more control, you can supply your own template; I have done so in the tint package (which is also on CRAN)

• if all that is in place, it is indeed just a call to rmarkdown::render(...)
