ESS/AucTeX/Sweave integration
Question
I'm using GNU/Linux distro (Arch, if that's relevant), Emacs v23.2.1, ESS v5.9 and AucTeX v11.86.
I want to setup AucTeX to recognize .Rnw files, so I can run LaTeX on .Rnw files with C-c C-c
and get .dvi file automatically. I reckon it's quite manageable by editing .emacs file, but I still haven't got a firm grasp on Elisp.
Yet another problem is quite annoying - somehow, LaTeX is not recognizing \usepackage{Sweave}
in preambule, so I actually need to copy Sweave.sty
file (in my case located in /usr/share/R/texmf/Sweave.sty
) to directory where .Rnw file is located (and I'm becoming more frustrated by the fact that this is common bug on Windows platforms!)
My question boils down to two problems:
- how to make LaTeX recognize
\usepackage{Sweave}
(without copyingSweave.sty
to "home" folder each time) [Edit: managed to do this; see comment after Dirk's answer] - how to setup AucTeX to compile .Rnw files to .dvi
Solution
That's two different questions.
For the first one, my Debian R packages make sure that there is a soft link from the $RHOME/share/texmf/
directory into the TeX file system tree, e.g. as /usr/share/texmf/tex/latex/R
.
For the second question: dunno. I tend to run Sweave via a small shell script I crafted years ago even though I do all the editing in Emacs.
Edit, a few months later: Use ESS, rather than AucTeX. Then M-n s
(i.e Alt-n followed by s) runs the Sweave step and M-n P
runs the LaTeX compilation, with a call to Bibtex if needed.
OTHER TIPS
After brief and efficient Googling, I've found this link, and at first glance, everything seems OK, but pdf file gets garbled after Sweaving... So I tackled this problem another way around: when in doubt, go bash! I've shamelessly stolen error checking function from Dirk's Sweave bash script available here. Basically, this is a workaround: R CMD Sweave
gets executed on .Rnw file, hence latex comes in, and pdflatex after that...
I'll post a bash script that does the job for me. I must state that I'm not an advanced bash programmer, moreover I'm not even a programmer by vocation, so there's a great chance that this script can be optimized/written properly. Here goes:
#!/bin/bash
FILEBASE=${1%.*}
FILEXT=${1##*.}
FILEPATH=${1%/*}
TEXFILE=$FILEBASE.tex
PDFFILE=$FILEBASE.pdf
# errorexit
function errorexit () {
echo "Error: $1"
exit 1
}
# check if file exists
if [ ! -f $1 ]; then
errorexit "File $1 not found!"
else
# check for filename length
if [ ${#1} -lt 1 ]; then
errorexit "Need to specify argument file!"
else
# if filelength OK, check extension
if [ $FILEXT != "Rnw" ]; then
errorexit "You must pass Sweave (.Rnw) file!"
# finally, run Sweave
else
cd $FILEPATH && R CMD Sweave $1
# latex $TEXFILE
pdflatex $TEXFILE
# xdg-open $PDFFILE
fi
fi
fi
Then save/copy/move this script in any of echo $PATH
folders (I keep mine in /usr/bin/
), and make sure that it's named sweave, or choose whatever name you like, then put these lines in your .emacs file:
(global-set-key (kbd "C-c s")
(lambda ()
(interactive)
(shell-command (concat "sweave " buffer-file-name))))
Of course, you can change keybinding to suite your needs, and be sure to change sweave with script name placed in /usr/bin/
.
Bare in mind that this is not an answer, but a workaround. If you have found a way to deal with AucTeX/ESS/Sweave integration, post it, and I'll give it a checkmark.
Prior to this workaround, I had to do M-n s
to Sweave, followed by C-c C-c
which is default keybind in AucTeX for LaTeX file compilation. Produced file is erroneous, so I had to give it a try with bash. It works for me, if you have any suggestions, please let me know.
Kind regards,
