## TikZ
```{r}
options(
tinytex.engine = "xelatex",
tikzDefaultEngine = "xetex"
)
```
The figure generated by TikZ code is normal when the output is PDF while abnormal when output is HTML.

发现 figure-html/ 目录下的 fig-tikz-1.pdf 文件要比 figure-pdf/ 目录下的文件 fig-tikz-1.pdf 小得多。 （908B vs 2KB）
用函数 pdftools::pdf_info() 检查figure-html/ 目录下的 fig-tikz-1.pdf 文件，发现上述错误来自该 fig-tikz-1.pdf 文件，该文件已被损坏。（说明 pdftools 和 magick 都没问题，问题应该是来自 knitr 或 rmarkdown?）
奇怪的现象发生了，为什么输出格式设定 HTML 时，编译同样的 TikZ 代码得到错误的 PDF 图片文件？
在 MacOS 上，文档输出格式无论是 HTML 还是 PDF ，结果都是正常的，没有报错。
