running R in batch-mode - print to screen?

Question

When running

R CMD BATCH [options] filename.r

I want to control where the output is printed. I can suppress the creation of the .Rout file with

R CMD BATCH [options] filename.r /dev/null

but is it possible to direct the output to the screen? Like when I run it by

R [options] < filename.r

?

Answer 1

Guess you're on linux. Tried already to redirect to /dev/console ?

Edit -add info from the comments -:

/dev/console apparently doesn't work, /dev/tty does. Depending on the system, /dev/tty0 might be an option too

Cheers

Answer 2

Try Rscript or R --no-save < filename.R:

biocoreap1:Desktop vinceb$ Rscript test.R
test
biocoreap1:Desktop vinceb$ R --no-save < test.R
