在 tufte_handout 中使用 Tikz 和 RMarkdown

Question

我正在尝试使用tufte_handout 在 R Markdown 中生成 tikz 图形，我正在 RStudio 中运行它。这是我的sessionInfo()：

    R version 3.3.2 (2016-10-31)
    Platform: x86_64-apple-darwin16.1.0 (64-bit)
    Running under: macOS Sierra 10.12.2

    locale:
    [1] en_US.UTF-8/en_US.UTF-8/en_US.UTF-8/C/en_US.UTF-8/en_US.UTF-8

    attached base packages:
    [1] stats     graphics  grDevices utils     datasets  methods   base     

    loaded via a namespace (and not attached):
     [1] backports_1.0.4 magrittr_1.5    tufte_0.2       rprojroot_1.1   htmltools_0.3.5 tools_3.3.2     yaml_2.1.14     Rcpp_0.12.8    
     [9] stringi_1.1.2   rmarkdown_1.3   knitr_1.15.1    stringr_1.1.0   digest_0.6.11   evaluate_0.10  

我的例子（还没有工作）是：

     ---
     title: "TikzTest"
     output: 
       tufte::tufte_handout: default
     ---

     This is a test of the R Markdown tufte_handout.^[This is a sidenote in the tufte_handout] To use the tikz package, you have to include this code chunk:
     ```{r setup, include=FALSE}
     knitr::opts_chunk$set(echo = TRUE,dev = 'tikz')
     library(tikzDevice)
     ```

     But it doesn't work?:
     ```{r,engine='tikz'}
     \begin{tikzpicture}[line width=0.05cm]

     \node [align=center] (x) at (0,0) {$X$};
     \node [align=center] (y) at (2.55,0) {$Y$};

     \begin{scope}[line width=.05cm,shorten >= 5pt, shorten <= 5pt]
     \draw[->,color=black] (x) to (y);
     \end{scope}
     \end{tikzpicture}
     ```

当我编织这个时，我收到以下错误：

     Error in tools::texi2dvi(texf, pdf = !to_svg, clean = TRUE) : 
       Running 'texi2dvi' on './tikz145322b8f468.tex' failed.
     Messages:

     Execution halted

我已经安装了 MacTeX-2016 分发版

我没有 Mac，但在运行您提供的代码时遇到了同样的错误。为了解决这个问题，我所要做的就是采取这一行：

line:knitr::opts_chunk$set(echo = TRUE,dev = 'tikz')

并将其更改为以下内容：

knitr::opts_chunk$set(echo = TRUE)

通过这种更改，它与我想象的您正在寻找的输出效果很好。希望这也适用于 Mac。
