在带有RMarkdown的tufte_handout中使用Tikz

Question

我正在尝试使用我在RStudio中运行的tufte_handout在R Markdown中生成tikz图。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(还没起作用)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}
     ```

当我编织这个的时候，我得到了以下错误：

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

     Execution halted

我安装了MacTeX-2016发行版

我没有Mac，但在运行您提供的代码时，我收到了与您相同的错误。要修复它，我所要做的就是使用下面这行代码：

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)

有了这样的改变，它就能很好地处理我想要的输出。希望这也能在Mac上运行。
