More efficient R / Sweave / TeXShop work-flow?

问题

I've now got everything to work properly on my Mac OS X 10.6 machine so that I can create decent looking LaTeX documents with Sweave that include snippets of R code, output, and LaTeX formatting together. Unfortunately, I feel like my work-flow is a bit clunky and inefficient:

Using TextWrangler, I write LaTeX code and R code (surrounded by <<>>= above and @ below R code chunk) together in one .Rnw file.
After saving changes, I call the .Rnw file from R using the Sweave command
```
Sweave(file="/Users/mymachine/Documents/Assign4.Rnw", 
        syntax="SweaveSyntaxNoweb")
```
In response, R outputs the following message:

You can now run LaTeX on 'Assign4.tex'

So then I find the .tex file (Assign4.tex) in the R directory and copy it over to the folder in my documents ~/Documents/ where the .Rnw file is sitting (to keep everything in one place).
Then I open the .tex file (e.g. Assign4.tex) in TeXShop and compile it there into pdf format. It is only at this point that I get to see any changes I have made to the document and see if it 'looks nice'.

Is there a way that I can compile everything with one button click? Specifically it would be nice to either call Sweave / R directly from TextWrangler or TeXShop. I suspect it might be possible to code a script in Terminal to do it, but I have no experience with Terminal.

Please let me know if there's any other things I can do to streamline or improve my work flow.

回答1:

One-click Sweaving is easy to do in TeXShop using the Sweave.sh script by Gregor Gorjanc. Get it from http://cran.r-project.org/contrib/extra/scripts/Sweave.sh and put it in your ~/Library/TeXShop/bin/ folder.

Then add the following files to your ~/Library/TeXShop/engines/ folder:

As Sweave.engine:

#!/bin/bash
~/Library/TeXShop/bin/Sweave.sh  -ld "$1"

As SweaveNoClean.engine:

#!/bin/bash
~/Library/TeXShop/bin/Sweave.sh  -nc -ld "$1"

You'll have to set the permissions on Sweave.sh and the two engine files to allow execution.

To Sweave with one click, restart TeXShop after adding these files, open the Sweave document (with Rnw extension) and in the dropdown menu above the document window, change it from LaTeX to Sweave or SweaveNoClean.

BEWARE: The "Sweave" option wll clean up after itself, deleting all the extra files LaTeX and Sweave creates. If your file is called myfile.Rnw, this will include files called myfile.R and myfile.tex. So a word to the wise: make sure the basename of your Rnw file is unique; then nothing unexpected will be written over and then deleted.

The SweaveNoClean option does not clean up after itself. This makes sure you don't delete anything unexpected; though it could still write over a file called myfile.tex if you Sweave a myfile.Rnw. This also doesn't delete any graphics that have been created, in case you want to have them separate from your full typeset document.

I use a Makefile of the following form for my Sweave documents:

pdf: myfile.tex
    R CMD texi2pdf myfile.tex

myfile.tex: myfile.Rnw
    R CMD Sweave myfile.Rnw

Then I can build the document in one step in the Mac OS Terminal by running the command make pdf

I'm sure there is a way to bring this closer to your one-click goal in Mac OS X, but this works well enough for me.

回答3:

On the bash shell command line:

R CMD Sweave foo.Rnw && pdflatex foo.tex

Runs Sweave, and if that succeeds it goes on to do pdflatex. Out pops a pdf. If you've got this in a bash Terminal then just hit up-arrow to get it back and do it again. And again. And Again.

Makefile solution also good.

回答4:

RStudio has a button that does this in one go. One caveat is that it runs in its own session, so any workspace variables you may have set are ignored.

回答5:

Just a note: you can actually call things like pdflatex etc. directly from R using texi2dvi (in the tools package). For example:

Sweave(file="/Users/mymachine/Documents/Assign4.Rnw")

texi2pdf("Assign4.tex")

would compile your Rnw file into a pdf. Thus, no need to leave R to handle the tex->pdf step.

回答6:

I use these (saved as sweave.engine and sweavebibtex.engine) for custom engines in texshop. I usually work up a code chunk in R, then copy the block into the rnw file I have open in texshop. I'd love a solution that lets me do syntax highlighting and spelling correction of R and tex in the same document (that isnt emacs).

#!/bin/bash
echo 'SWEAVE | PDFLATEX. Custom engine--Akasurak-16Nov2009'
export PATH=$PATH:/usr/texbin:/usr/local/bin
R CMD Sweave "$1"
pdflatex "${1%.*}"

and the second, for doing bibtex as well:

#!/bin/bash
date
before="$(date +%s)"
echo 'SWEAVE | PDFLATEX | BIBTEX | PDFLATEX | PDFLATEX. Custom engine--Akasurak-16Nov2009'
#Updated 20Jul2010 for auto including Sweave.sty


export PATH=$PATH:/usr/texbin:/usr/local/bin

R CMD Sweave "$1"
R CMD pdflatex "${1%.*}"
bibtex  "${1%.*}.aux"
R CMD pdflatex "${1%.*}"
R CMD pdflatex "${1%.*}"


after="$(date +%s)"
elapsed_seconds="$(expr $after - $before)"
date
echo Elapsed time '(m:s)': $(date -r $elapsed_seconds +%M:%S)

Can't say they are the best way of doing things, but they do work.

回答7:

I use either Aquamacs or Eclipse to do the editing of the .Rnw file, then I use the following shell function to compile & view it:

sweaveCache () {
  Rscript -e "library(cacheSweave); setCacheDir(getwd()); 
    Sweave('$1.Rnw', driver = cacheSweaveDriver)" && 
  pdflatex --shell-escape $1.tex && 
  open $1.pdf
}

Notice that I'm using the cacheSweave driver, which helps avoid constantly re-executing code sections that take a long time to run.

BTW, I'm also trying to switch over to Babel instead of Sweave; not sure which I'll end up using more often, but there are definitely aspects of Babel that I like.

回答8:

The best solution is here: you create a new *.engine for TeXShop to use, then typeset using the shortcut or the 1 button.

Cameron is also very responsive, so I highly recommend his solution.

回答9:

If you are open to switching to a (paid) solution, TextMate has a Sweave plugin that takes you from .Rnw to PDF in one step: Sweave, typeset, and view. Combined with Skim, which can be configured to reload PDFs, it makes tweaking files pretty easy.

回答10:

I had this same issue (I use Mac OSX) and I opted to download Eclipse Classic 3.6.2. and then installed the StatET plugin. It's a bit hairy to get set up but once you do this environment is nice because you can one-click compile your .Rwn Sweave document using pdflatex and set options for your favorite viewer so the .pdf automatically pops up when you compile like it does in TeXShop. You can do this in TeXShop as well, but TeXShop is lousy for debugging .Rnw files and it doesn't highlight the R-code in the .Rwn file. In Eclipse you can customize the syntax highlighting (not the greatest from the Texclipse end, but ok) so that you can easily distinguish between your R and LaTeX code. You can also launch the R console from within Eclipse and it has a graphical object browser. Anyway, I could go on. If you want details about how to get it all installed, message me.

Guess I'm late to the party on this, but I put together a webpage that documents my Sweave workflow based on Eclipse (with one-touch sweave):
