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

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 pdfl开发者_开发知识库atex does not find the file because it's always written to the HOME directory of my user.

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.

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
