Why? Cygwin and Sweave get along very well. Here is a little utility script
I use:

nbkh85c at minot:~> cat bin/sweave 
#!/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
				    
PDFFILE=$BASENAME.pdf
filetest $PDFFILE && acroread `pwd`/$PDFFILE &  



Note that it needs another three line script acroread which uses cygpath to
translate the path to the actual pdf file so that the windows binary can
grok it.
