Question

我是R的新手并且一直试图在R markdown中编写我的项目报告。但是我遇到了问题。我尝试在堆栈溢出以及其他网站上实现解决方案，但我无法取得进展。

详细说明：

R version 3.2.1（2015-06-18） - “世界着名的宇航员”

Mac OS X Yosemite版本10.10.5

已安装pandoc 1.15.0.6 https://github.com/jgm/pandoc/releases/tag/1.15.0.6

来自http://tug.org/mactex/的MacTeX-2015分发

MacTEX都-20150613

在Global选项下，我使用knitr编织Rnw文件，使用XeLaTex将Typeset LaTeX编织成PDF，在编译后取消选择干净的辅助输出。

我收到以下错误：

输出文件：07.Random_Forest.knit.md

/ usr / local / bin / pandoc 07.Random_Forest.utf8.md - 来自markdown + autolink_bare_uris + ascii_identifiers + tex_math_single_backslash-implicit_figures --output 07.Random_Forest.pdf --template / Library / Frameworks / R.framework / Versions / 3.2 / Resources / library / rmarkdown / rmd / latex / default-1.14.tex --highlight-style tango --latex-engine / Library / TeX / texbin / pdflatex ！未定义的控制序列。 l.921 {\ centering \ includegraphics

附上我的R降价代码的一部分以供参考：

感谢您的时间和帮助。

Pandoc不知道您的输出包含图形，因为您使用了块选项fig.align = 'center'。您可以将graphics: yes添加到R Markdown文档的YAML元数据中。
