[R] get plot in a window when running R in the shell

[bogdan romocea]

Dear useRs,

On a GNU/Linux box I want to run some code from the command line. This works
   #!/bin/sh
   R --vanilla -q --gui=X11 < code.r
however I want the plots to appear in a window (as it happens when the
code is run interactively) instead of being saved in 'Rplots.ps'. Is
that doable?

Thank you,
b.
