img.raw is intended to represent the name of a raw R object, not a file name.<br><br><div class="gmail_quote">On Sun, Dec 6, 2009 at 3:25 PM, Gabor Grothendieck <span dir="ltr"><<a href="mailto:ggrothendieck@gmail.com">ggrothendieck@gmail.com</a>></span> wrote:<br>

There has been a recent discussion about allowing devices to output to connections on r-devel and apparently this has languished for years despite Jeffrey Horner posting code which would have allowed it 3 years ago. Would it be a problem for tikz to handle that even if the other devices don't? For example, Hadley Wickham had posted this proposed functionality:<br>
<br>rc <- <span>rawConnection</span>("raw.img", "w")<br>
png(rc)<br>
<div>plot(1:10)<br>
dev.off()<br>
</div>close(rc)<br>
<br>where in this case png() would be replaced with tikz().<div><div></div><div class="h5"><br><br><div class="gmail_quote">

Great. Just one other related comment. I think I would likely use the tikz(..., append=TRUE) style but some might prefer to use sink. That could be done if it were possible to write the output to stdout like this. If its not a problem you might want to add that too.<br>
<br>sink("myfile.tex")<div><br>cat("\\documentclass{article}<br>\\usepackage{tikz}<br>\begin{document}<br>\\begin{figure}[ht]<br>\\centering<br></div>")<br># "" or "stdout" or default writes to stdout<br>
tikz(width=5, height=5)<div><br>x <- rnorm(100)<br>plot(x)<br></div><div>dev.off()<br>cat("\\caption{caption}<br>\\label{fig:inline}<br>\\end{figure}<br>\\end{document}<br></div>")<br>sink()<div>

I liked this idea so much that I implemented it right away. You can<br>
get it from the master branch of my github fork until the next release<br>
<br>

Instead of "append" i called it "console." It works nearly as you envisioned:<br>
<div><br>
cat("\\documentclass{article}<br>
\\usepackage{tikz}<br>
<br>
\\begin{document}<br>
\\begin{figure}[ht]<br>
\\centering<br>
", file = "myfile.tex")<br>
<br>
</div>sink("myfile.tex",append=T)<br>
tikz(console=T, width=5, height=5)<br>
<div><br>
x <- rnorm(100)<br>
plot(x)<br>
</div>quiet <- dev.off()<br>
sink()<br>
<div><br>
cat("\\caption{caption}<br>
<br>
\\label{fig:inline}<br>
\\end{figure}<br>
\\end{document}<br>
", file = "myfile.tex", append = TRUE)<br>
<br>
</div>The following will now produce a self contained tex file:<br>
<div><br>
\documentclass{article}<br>
\usepackage{tikz}<br>
\usepackage[nogin]{Sweave}<br>
\begin{document}<br>
\begin{figure}[ht]<br>
\centering<br>
<<inline,echo=F,results=tex>>=<br>
<br>
require(tikzDevice)<br>
</div> tikz(console=T,width=5,height=5)<br>
<div> x <- rnorm(100)<br>
plot(x)<br>
</div> dummy <- dev.off()<br>
<div><br>
@<br>
\caption{caption}<br>
\label{fig:inline}<br>
\end{figure}<br>
\end{document}<br>
