Hi,
Currently the R script I have is executed with this command:
$ R CMD BATCH mycode.R
And the output is stored in mycode.Rout.
Is there a way I can issue command from shell (like above)
so that the output is printed to STDOUT?
It's troublesome to open the "Rout" file every time to debug.
Under a Unix system you could try to pipe the command into tail -f
i.e.,
$ R CMD BATCH mycode.R | tail -f
That should display the file as it gets written.
Buffering may get in the way -- so 'gets written' may be much later than
when it is output by R.
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.
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.
