问题
I have a problem with tikzDevice. I'm using the latest versions of R (with latest knitr and tikzDevice packages) and RStudio, updated TeX Live to 2015 binaries (and I think I have all the required packages).
When I try to output graphics to tikzDevice, compilation hangs. Other graphics devices like PDF or CairoPNG work without a problem.
As an example, I tried to compile a the simple code below from RStudio with XeLaTeX (set as the default LaTeX compiler in RStudio), but it hangs forever after using the TikZ metrics dictionary.
What I see is that the compilation actually produces a file with .tikz extension in the "figure" folder, which can be successfully compiled if I run XeLaTeX on it.
I attached below the complete log from RStudio 'Compile PDF' console output pane while it hangs:

In addition, if I run the command knit("test.Rnw") from R console, I get this:

Error: failed to compile figure/graphics-fig1-1.tikz to PDF
In addition: Warning message:

Though, again if run xelatex on the .tikz graphics file from a windows command prompt, it successfully compiles to PDF.

Following up on my problem with tikzDevice, the only workaround I found is to output the graphics to another device like png, add usepackage{tikz} to the preamble, call tikz() inside the code chunk and \input{} the resulting .tex figure like this:
\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}
This way I can get the consistency of fonts from using tikz, but it would be much easier to have tikzDevice() to work.
