[R] non-interactive R usage...

I just try the following on Linux (Mandrake7.1) and it works:
>From the shell prompt:
R --no-save < tryplot.R > tryplot.Rout
This generated the JPEG file, and dump the R session text to tryplot.Rout.
If I understand correctly, jpeg() will *not* work with R BATCH, since it
depends on x11(), and x11() isn't available when run under batch mode.
