Working comfortably with (X)Emacs + Sweave

I would appreciate if people told me how they solve these problems or
have found any other way to make Xemacs more comfortable. A
"call sweave and then latex on this file in one go" and "show the DVI
that was produced from this Rnw file" command would be very
useful. Emacs init.el files and similar would help a lot, too.

Excellent question. Below is my pedestrian answer. I edit in XEmacs,
and then call this shellscript. You could also bind it to what gets 
called from latex/auctex when you 'compile' the input file.

#!/bin/bash -e

function errorexit () {
    echo "Error: $1"
    exit 1
}	

function filetest () {
    if [ ! -f $1 ]; then
       errorexit "File $1 not found"
    fi
    return 0
}
		       
	       
if [ "$#" -lt 1 ]; then
    errorexit "Need to specify argument file"
fi
			   
		   
BASENAME=$(basename $1 .Rnw)
			   
RNWFILE=$BASENAME.Rnw
filetest $RNWFILE
echo "library(tools); Sweave(\"$RNWFILE\")" \
      | Rterm --no-save --no-restore --slave
			       
LATEXFILE=$BASENAME.tex
filetest $LATEXFILE && pdflatex $LATEXFILE

Dear List,

I am trying to become more familiar with Sweave at the moment, beacuse
I am convinced that it will eventually make my life easier. However,
I have not found anything relevant in the mail archives about the
following problem.

Both the article in R-News and the Sweave FAQ suggest that Emacs would
be a great development environment for working with Sweave. So far, it
doesn't seem to fit that description... Maybe I'm doing something
wrong. I am going to describe the way I do things, and hope that
people on this list can suggest something more comfortable.

I edit the file in one buffer and keep one open for the R prompt.
Every time I need to recompile the whole document (Sweave to, say,
DVI) I go through the following:

1. call sweave manually via the R prompt
2. open the resulting LaTeX file (I have not found a way to refresh
this, maybe there's some magical XEmacs keystroke that rereads the
file from the disk?, so I keep opening/closing it)
3. compile the LaTeX file

This is a bit tedious as I like to compile often, because I like to
see the way my document looks (I know that TeX is WYSIWYM, but I
prefer to check my formulas instantly).

I would appreciate if people told me how they solve these problems or
have found any other way to make Xemacs more comfortable. A
"call sweave and then latex on this file in one go" and "show the DVI
that was produced from this Rnw file" command would be very
useful. Emacs init.el files and similar would help a lot, too.

Or maybe I am just trying to use things the wrong way, if so, please
enlighten me ;-) If this is not how people use Sweave+Emacs, then tell
me how I should do it.

Thanks in advance,

Tamas Papp
