R CMD BATCH --vanilla --slave produces unwanted lines

Anyway, now I'm trying to run R in batch mode, but I'm getting extra
output, which I don't want (RedHat 8.3, R-1.7.0):

...

r:~% R CMD BATCH --vanilla --slave test.R

Why not just run:
unix> R --vanilla --slave < test.R > test.out

Then the "options(echo=FALSE)" line is unnecessary.  Note an explicit q()
at the end of the script eliminates a single blank line that occurs otherwise.
So the test.R script is just:

  write(rnorm(4),"")
  q()
