What is the correct format for the shebang line and what options are

I find plenty of blogs and opinions, but few authoritative answers.
The authoritative source for the options is the R help page ?Rscript.
The authoritative answers for the format are likely slightly more
difficult, because it is your shell that processes the file, it's not R
handling the command line. But ?Rscript does give examples.

I want an R script to run and update packages periodically, with a
cron job that launches it. What is necessary to put in
line one of the R program. Aside from the basic part
#!/usr/bin/Rscript
what else can there be, or should there be?
Various people suggest adding things like --vanilla but those seem
not to be accepted, at least on RedHat EL 6 with R-2.15.1. I'd like
to run this with a command line like:
$ R-labSelectInstall-02.R /tmp/Rupdate.txt 21
so that all the standard output and err goes to a text file, but I've
not found a way to make it work comparably to the R command line
option --vanilla or such.
# ./R-labSelectInstall-02.R --vanilla
'ARNING: unknown option '--vanilla
See what I mean?
