[R] Displaying Grahics to the X Window when calling R from command line

[Pologruto, Thomas]

Thank you for your response.  I tried searching the archives but did not
know that it was called X11() device.

Can this be done in version 2.6.2 or do I need to have version 2.7.0
running?  Also, when you say wait in my script, I need to put a sleep or
something in the script or else it will delete the plot when the script
exits?

Thanks you again,
Tom

The issue is that the X11() device is the default device only in
interactive use, and further than the event loop is only run in
interactive use.

You need to

1) make use of R 2.7.0 RC
2) call R with R --vanilla --interactive
3) arrange for your script to wait for something so the plot remains up.

This has come up before, so please search the archives for more details.

I think it does, on a PostScript or PDF file.
