See
man R
for how to do it, although I'm not sure where it says the
following:

To get just the print output and nothing else, it helps to have
print()'s in the script itself.  Then you can use

R --slave < myfile.R > printoutput.txt

I also use R --vanilla < myfile.R
for a R file that has write.table()'s in it.  For this you do not
need to pipe the output anywhere.
