How can I change the output directory of R CMD Sweave?

Question

The question title says it all. Using R CMD Sweave my .tex file is always generated in my HOME directory. Is it possible to change this? I mean i could mv it with a shell script, but I guess there`s some better trick to do it :)

@Dirk: I used the script that I posted here and pdflatex does not find the file because it's always written to the HOME directory of my user.

Answer 1

Huh? It's always in the current working directory. So try

 mkdir foo
 mv whatever.Rnw foo
 cd foo
 R CMD Sweave whatever.Rnw

and whatever.tex will now be ~/foo because that is where you a) put the source and b) invoked the command.

Answer 2

So here's what worked for me... No argument for R CMD Sweave but still a workaround. the use of basename and dirname helped a lot :)

#!/bin/bash

myfile=$(/usr/bin/osascript << EOT
tell app "AppleScript Runner"
activate
    return posix path of (choose file)
    end
    EOT)

    if [ $? -eq 0 ]
    then
        echo $myfile
        R CMD Sweave $myfile
        no_ext=`basename $myfile .Rnw`
        directory=`dirname $myfile`
        mv ~/$no_ext.tex $directory/$no_ext.tex
        /usr/local/texlive/2009/bin/universal-darwin/pdflatex -output-directory       $directory $no_ext.tex
        open $directory/$no_ext.pdf
        else
            echo "User canceled"
            fi
