How to suppress R startup message?

Question

Running on Windows 7

rterm < foo.r > temp.txt

The output file starts with:

R version 3.0.1 (2013-05-16) -- "Good Sport"
Copyright (C) 2013 The R Foundation for Statistical Computing
Platform: x86_64-w64-mingw32/x64 (64-bit)

R is free software and comes with ABSOLUTELY NO WARRANTY.
You are welcome to redistribute it under certain conditions.
Type 'license()' or 'licence()' for distribution details.

and further text.

How do I suppress this message? I did not see an option to do this in the Rprofile.site file. Of course I can use another program to delete the first N lines of the output file, but it is more elegant to suppress the startup message?

Answer 1

Invoking R from the command line:

--quiet
--silent
-q

Do not print out the initial copyright and welcome messages.

--slave

Make R run as quietly as possible. This option is intended to support programs which use R to compute results for them. It implies --quiet and --no-save.
