Not quite.  You need to use eg

R <infile.r >outfile.log &

to take commands from infile.r and send output to outfile.log.  It is
sensible to explicitly put 
at the end of your file if you want created variables to be saved in
.RData. At the moment q("yes") is the default but there have been efforts
to get this policy changed, so I wouldn't rely on it.

Also note that a bug in R0.49 causes a stack imbalance if there is an
error reported in the file.
