Is there a way to keep the code and the figure together in knitr when using a figure environment in LaTeX?
This style:
\documentclass{article}
\begin{document}
writing
<<cars, fig.cap="this is a figure.">>=
with(mtcars, plot(mpg, disp))
@
writing
\end{document}
will result in the figure being in a float in LaTeX -- which is what I want, except that the figure can float away from the code.
My current workaround is writing the figure environment in LaTeX manually:
\begin{figure}
<<cars2>>=
with(mtcars, plot(mpg, disp))
@
\caption{this is a figure.}
\end{figure}
Is there a more elegant way that I can do this in knitr? Adding the fig.pos='h' option is not enough. fig.show='asis' also does not get it done.
Do I have to write my own hook? Can this be done easily?
