I'm trying to find out what people use for editing .Rnw files.
Desirable features are:
R code completionLaTeX code completionR function documentationR console access R code and LaTeX codeR code. With this, the user highlights a chunk of code that produces a value and the tool converts this into a function with the appropriate inputs and value.knitr has a few pretty straightforward ways of handling this.
knit_child() with inline R codeSay your setup is like the following. In the same directory, you have:
graph.R## ---- graph
library(ggplot2)
CarPlot <- ggplot() +
stat_summary(data= mtcars,
aes(x = factor(gear),
y = mpg
),
fun.y = "mean",
geom = "bar"
)
CarPlot
chapter1.RnwHey, look, a graph (Figure~\ref{fig:graph})!
<<graph, echo=FALSE, message=FALSE, fig.lp='fig:', out.width='.5\\linewidth', fig.align='center', fig.cap="A graph", fig.pos='h!'>>=
@
main.Rnw\documentclass{article}
\begin{document}
<<external-code, echo=FALSE, cache=FALSE>>=
read_chunk('./graph.R')
@
\Sexpr{knit_child('chapter1.Rnw')}
\end{document}
Then, you can knit the main.Rnw file and compile the resulting .tex file with either pdflatex or xelatex.
The output is:
Note that you can also read the external .R file from the child .Rnw file.
So, the following would have worked just as well.
chapter1-mod.Rnw<<external-code, echo=FALSE, cache=FALSE>>=
read_chunk('./graph.R')

main-mod.Rnw\documentclass{article}
\begin{document}
\Sexpr{knit_child('chapter1-mod.Rnw')}
\end{document}
childAssuming you have graph.R and chapter1.Rnw from above in the same directory, then your main.Rnw should be:
\documentclass{article}
\begin{document}
<<external-code, echo=FALSE, cache=FALSE>>=
read_chunk('./graph.R')
@
<<child-demo, child='chapter1.Rnw'>>=
@
\end{document}
Note that you can also read the external .R file from within the child document in this case, too.
So, assuming you had graph.R and chapter1-mod.Rnw from above in the same directory, then your main-mod.Rnw file should be:
\documentclass{article}
\begin{document}
<<child-demo, child='chapter1-mod.Rnw'>>=
@
\end{document}
I have solved it.
The command I use in the user-defined commands for compiling and displaying a Rnw-file in my own pdf-viewer is :
"C:/whateverYourPathToRonYourMachineIs/R-3.0.1/bin/Rscript.exe" -e "library(knitr); knit2pdf('%.Rnw')" | pdflatex -synctex=1 -interaction=nonstopmode %.tex | "C:/whateverYourPathToYourPDFViewerOnYourMachineIs/Foxit Reader.exe" "?am.pdf"

Personally, I like emacs+ess+auctex. I think it hits all your points, but unfortunately it has an epic learning curve.
