[R] tikzDevice and Sweave

[Yihui Xie]

Yeah, the philosophy of knitr from the very beginning is that if you
want to draw a plot, simply draw it, and knitr will take care of the
rest of work (http://i.imgur.com/jrwbX.jpg). You rarely need to think
about graphical devices or LaTeX or a specific output format. With
knitr, the example can be reduced to the absolutely minimal:

\documentclass{article}
\begin{document}
<<tikzFig, echo=FALSE, dev='tikz', fig.width=4, fig.height=3>>=
plot(sin, -pi, 2*pi, main = "A stand alone TikZ plot", xlab = "x",
ylab = "sin(x)")
@
\end{document}


Regards,
Yihui
