从TeX源生成PDF时出错错误：pandoc文档转换失败，错误43暂停执行

Question

我是R的新手，一直试图用R markdown编写我的项目报告。 但是我正面临问题。 我尝试实现堆栈溢出以及其他网站上存在的解决方案，但是我无法取得进展。

细节：

R版本3.2.1（2015-06-18）-“举世闻名的宇航员”

RStudio版本0.99.441 –©2009-2015

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发行版

MacTEX都-20150613

在“全局选项”下，我已使用knitr编织了Rnw文件，使用XeLaTex将TypeLaTeX排版为PDF，并在编译后取消选择了干净的辅助输出。

我收到以下错误：

输出文件：07.Random_Forest.knit.md

随附我的R降价代码的一部分，以供参考：

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