RMarkdown/Pandoc无法使用乳胶颜色命令来编织Pdf [英] RMarkdown / pandoc fails to knit Pdf with latex color commands

问题描述

• Mac OS:10.11.6
• R版本:3.3.1
• MacTex:2016年/TexLive:6.2.2
• RMarkdown:1.0.9014
• 针织衫:1.14
• Pandoc:1.17

当乳胶命令(例如:

\textcolor{blue}{Character String} 

存在于.rmd文件中.错误输出为:

are present in the .rmd file. The error output is:

/usr/local/bin/pandoc + RTS -K512m -RTS test.utf8.md --to乳胶-from markdown + autolink_bare_uris + ascii_identifiers + tex_math_single_backslash --output test.pdf --template〜/R/3.3 /library/rmarkdown/rmd/latex/default-1.17.0.2.tex --highlight-style tango --latex-engine/Library/TeX/texbin/pdflatex --variable graphics = yes --variable'geometry:margin = 1in ' ！未定义的控制顺序. l.105 \ textcolor

Undefined control sequence. l.105 \textcolor

pandoc:生成PDF时出错

pandoc: Error producing PDF

错误:pandoc文档转换失败，错误43

Error: pandoc document conversion failed with error 43

执行停止

包含带有echo = TRUE的r代码块，例如:

Inclusion of an r code chunk with echo = TRUE such as:

```{r, echo = TRUE}
# I am a glitch 
```

.rmd文件中的

允许成功创建PDF文档.

in the .rmd file allows for the successful creation of the PDF document.

如果.rmd文件中的所有r代码块均使用echo = FALSE或等效语句设置，则如果存在诸如/textcolor之类的乳胶命令，则无论使用的乳胶引擎如何，PDF文件都不会编织.如果仅使用乳胶命令，例如\ begin {tabular}，许多等…，则不会出现该错误.

If all r code chunks in the .rmd file are set with echo = FALSE or equivalent statements, the PDF file will not knit regardless of latex engine used if latex commands such as /textcolor are present. If only latex commands such as \begin{tabular}, many, etc… are used the error is not present.

推荐答案

在YAML标头中添加标头包括:\ usepackage {color}" ，可以解决此问题.但是，目前尚不清楚为什么插入"echo = TRUE" R代码块也可以解决该问题.

Addition of "header-includes: \usepackage{color}" to the YAML header, as seen below, addresses the issue. However, it is unclear why insertion of an "echo = TRUE" R-code chunk also resolves the issue.

---
title: "test"
output: pdf_document
header-includes: \usepackage{color}
---

有趣的是，对于R-Studio套件的早期版本(如下所示)，在YAML标头中没有出现标头包括:\ usepackage {color}" ，在此之前并没有必要在.rmd文件中使用诸如"\ textcolor {blue} {Character String}" 之类的命令.

Interestingly, with a previous version of the R-Studio suite, as see below, inclusion of "header-includes: \usepackage{color}" in the YAML header, did not appear necessary prior to use of commands such as "\textcolor{blue}{Character String}" in the .rmd file.
