With all due respect, this really has nothing to do with R and Finance, and
is therefore not relevant to the list.

Further, it would even be off-topic on r-help.

Please see the R FAQ for the frequently asked question of how to run R in
BATCH mode. The R-Windows FAQ may have additional pointers.

In short, R CMD BATCH is your friend, but there are other ways too. Under
Cygwin etc you can also write shell scripts that pipe into R (so-called
"here" documents).

help.search("batch") would have pointed you there, RSiteSearch("R in batch
mode") also leads to numerous hits -- 460 when I just tried it.

Hell, there are no rules here - we're trying to accomplish something.
