我对tikzDevice有疑问。我使用最新版本的R（使用最新的knitr和tikzDevice软件包）和RStudio，将TeX Live更新为2015二进制文件（我认为我拥有所有必需的软件包） ）。
当我尝试将图形输出到tikzDevice时，编译挂起。其他图形设备（如PDF或CairoPNG也可以顺利运行。
作为示例，我尝试使用RStudio（XeLaTeX中设置为默认LaTeX编译器）从RStudio编译下面的简单代码，但它挂起使用TikZ指标字典后永远。
我看到的是，编译实际上在＆＃34;数字＆＃34;中生成了一个.tikz扩展名的文件。文件夹，如果我在其上运行XeLaTeX，则可以成功编译。
我附在RStudio＆＃39;编译PDF＆＃39;的完整日志下面。控制台输出窗格挂起时：

此外，如果我从R控制台运行命令knit("test.Rnw")，我会得到：

In addition: Warning message:

但是，如果从Windows命令提示符处xelatex图形文件上运行.tikz，它会成功编译为PDF。

跟我解决tikzDevice的问题，我找到的唯一解决方法是将图形输出到png等其他设备，将usepackage{tikz}添加到前导码中，在代码中调用tikz() chunk和\input{}得到的.tex数字如下：
\documentclass{article}
\usepackage{tikz}
\begin{document}
<<setup, include=FALSE, cache=FALSE>>=
library(knitr)
library(tikzDevice)
options(formatR.arrow=TRUE,width=50,tikzDefaultEngine='xetex')
opts_chunk$set(fig.path='figure/graphics-', cache.path='cache/graphics-', fig.align='center', dev='png', fig.width=5, fig.height=5, fig.show='hold', cache=TRUE, par=TRUE, concordance=TRUE)
@
\begin{figure}
<<fig1,eval=TRUE,echo=FALSE>>=
library(ggplot2)
setwd("~/")
td <- getwd()
tf <- file.path(td,'fig1.tex')
tikz(tf, standAlone=F, bareBones=F)
qplot(displ, hwy, data = mpg, colour = factor(cyl))
dev.off()
@
\input{fig1.tex}
\end{figure}
\end{document}
通过这种方式，我可以使用tikz获得字体的一致性，但让tikzDevice()更容易工作。
