R help - Oct 2003 - plotting graphs with Rterm

Hello,
I need to execute R code contained in  a file xxx.R from DOS.
The file is really simple, only:
> plot(rnorm(100))
When I launch Rterm from Dos command and then source the file xxx.R it
works, but I need to call the command from a DOS command file *.bat
Using Rterm --slave < xxx.R plots the graph in a postscript file Rplots.ps,
how can I do to get the graph in an R window.
Using a command windows() or win.graph() in the R file does not work any
more.

I have the same problem with tk widgets. If the file xxx.R
is:
>library(tcltk)
>tt<-tktoplevel()
The widget does not appear on the screen.

Does anybody can help?
Regards,

Eric

You have to specify the windows() device explicitly, if you are in 
non-interactive mode:

  windows()
  plot(rnorm(100))

It appears! I guess your R process has finished right after those lines 
and the window has been shut before you have seen it.
