[PATCH] Add tikzDevice support to ob-R

Aloha all,

The attached patch adds tikzDevice support to ob-R.  It requires that
the tikzDevice package be available to R, so it must be installed and
loaded.  Something like the following code in .Rprofile will load the
package by default:

old <- getOption("defaultPackages")
options(defaultPackages = c(old, "tikzDevice"))

Then, specify a .tex file in the :file header argument of the R source
code block, e.g., :file intervals.tex, and the graphic will be produced
by tikzDevice.

The advantage of this for LaTeX export is that the resulting file will
be set with the fonts of its surrounding document.

Something like this works for me, where the \sffamily command uses the
document's sans serif font and the file is called intervals.tex:

\begin{figure}[htb!]
  \centering
  \sffamily
  \input{../figure/intervals}
  \caption[Elapsed time between Polynesian colonization of Hawai`i and fire-pit use]{Elapsed time between Polynesian colonization of Hawai`i and fire-pit use.}
  \label{fig:elapsed-time}
\end{figure}
 
All the best,
Tom

Thanks a bunch.  I always use pgfSweave and thus I haven't really
managed to move from Rnw (LaTeX + R files) to Org file.

Are you aware of the very handy pgfsweave bin?  In the Arch R package it
is located in

 /usr/lib/R/bin/pgfsweave

First, you don't have to load tikzDevice. Second, It makes this very
nice notation valid in Rnw files:

#+begin_src latex
\begin{figure}[tbh]
\caption{Time series $x$ and $y$}\label{fig:ts1}
<<ts3xy-plot, echo=FALSE, fig=T, tikz=T, external=T, cache=F, echo=F, width=7, height=3, sanitize=T>>=
plot(x.ts)
lines(y.ts)
#abline(lm(y.fil~x.fil))
@
\end{figure}
#+end_latex

which translates to the following automatically:
#+begin_src latex
\begin{figure}[tbh]
\caption{Time series $x$ and $y$}\label{fig:ts1}
\tikzsetnextfilename{class3-ts3xy-plot}
\tikzexternalfiledependsonfile{class3-ts3xy-plot}{class3-ts3xy-plot.tikz}
\input{class3-ts3xy-plot.tikz}
\end{figure}
#+end_src

It also adds nice formatting of R chucks without the need other R
packages.

Thus, using pgfSweave over regular Sweave is just wonderful.  However, I
don't know whether it can integrate with Babel.

Thanks again.

–Rasmus
