Another option for R/LaTeX/Sweave editor

WinEdt is another good option for R/LaTeX/Sweave editing. I especially the feature of running "knitr + pdflatex" without opening a R terminal. Unfortunately it is a Windows-only software.

Rstudio vs. StatET

Rstudio wins in easy installation, smaller size, and intuitive user interface. StatET wins in graphical debugger and an outline view. Right now, StatET is a better choice for Sweave/Knitr/LaTeX authoring platform than Rstudio.

Emacs support for knitr

Here is a simple elisp script.

Knitr problem

I got some weird problem with my R workflow recently. For example, the very simple code chunk below:
--------------------------------------------------
\documentclass[preview]{standalone}

\begin{document}

\begin{figure}
<dev='tikz'>>=
library(ggplot2)
qplot(displ, hwy, data = mpg, colour = factor(cyl))
@
\end{figure}

\end{document}
--------------------------------------------------
would not build correctly. Sometimes it gave error message, sometimes it created empty page, etc. Installing the latest version of knitr from the github repo seemed to solve the problem.
