I'm a bit surprised this worked for you...did you customize your build
so that Rterm.exe is in \bin\ rather than a subfolder for its specific
architecture?

I did not see anyone else mention this, so I wanted to add that with R
CMD BATCH you can add the --slave argument to avoid needing to add
options(echo = FALSE) to all your scripts.  The --no-timing option
stops proc.time() from running at the end.

For example from the command prompt I can run 'sample.R' using 32 bit R:

C:\R\R-2.12.1\bin\i386\R CMD BATCH --slave --no-timing "sample.R"
"sampleout.txt"

HTH,

Josh
