Re: [R] Printing output in STDOUT

I don't have access to a Unix system right now to give this a try but it should be a work around until someone who knows more about R can come up with an answer.

Buffering may get in the way -- so 'gets written' may be much later than when it is output by R.

What is wrong with R --vanilla mycode.R or variants like R --no-save mycode.R R --no-save -f mycode.R or even Rscript mycode.R ? R CMD BATCH is intended (unsurprisingly) for batch use of R.

I like your suggestions below much better - saved away for future reference too.
