I would like to use the tikz plotting device for my document. I compile a *.Rnw file from RStudio and I get an error message as soon as I set
dev='tikz'
The error
The error message is that
Error in createLockFile(lockname): cannot create lock file
This error is documented in conjunction with other issues (e.g. see here https://github.com/Sharpie/RTikZDevice/issues/66), but I found the issue here is unrelated to what is documented elsewhere.
A reproducible example:
Please find below a reproducible example:
\documentclass{scrartcl}
\usepackage{color,graphicx}
\usepackage{tikz}
<<setup, message=FALSE, cache=FALSE, echo=FALSE>>=
#Set your chunk options here
opts_chunk$set(fig.path='figure/graphics-', cache.path='cache/graphics-', fig.align='center', fig.width=13.69, fig.height=6.27, dev='tikz', fig.keep='last', cache=TRUE, par=TRUE, echo=FALSE, message=FALSE, warning=FALSE, results= 'hide')
# Also load ggplot
library(ggplot2)
@
\begin{document}
\begin{figure}[h]
<<plot>>=
data <- data.frame(some.data = rnorm(10))
p1 <- ggplot(data, aes(x=1:10, y=some.data)) + geom_point() + ylab(expression(X[t]))
p2 <- ggplot(data, aes(x=1:10, y=some.data)) + geom_line() + ylab(expression(X[t]))
library(gridExtra)
grid.arrange(p1, p2, ncol=1)
@
\end{figure}
\end{document}
and my session info is
R version 3.0.2 (2013-09-25)
Platform: x86_64-w64-mingw32/x64 (64-bit)
attached base packages:
[1] stats graphics grDevices utils datasets methods base
other attached packages:
[1] tikzDevice_0.7.0 filehash_2.2-2
loaded via a namespace (and not attached):
[1] grid_3.0.2 tools_3.0.2
together with RStudio Version 0.98.501
The problem
The problem seems to occur when I want to arrange the ggplots p1 and p2 using the package gridExtra. I.e. when I plot the graphs individually without arranging them the code works, but it seems not to be able to handle the grid.arrange command. Is there any way to arrange plots such that tikz works?
Many thanks!
