In short, I think "R CMD BATCH script " does what you want.
I routinely run R from scripts and use nohup, the two should work well
together AFAIK. I have encapsulated R stuff into a script ( "myR") 
and have something like this ,

if [ "$1" == "-run" ]
then
echo running $2
$R CMD BATCH $2
shift ; shift
fi


if [ "$1" == "-go" ]
then
echo starting R with no params
$R
shift
