[R] pgup/pgdown in R Graphics Window under Linux

2007-07-05 Thread Paul Matthias Diderichsen
Dear S-users.
This should be an easy one: How do I change pages on an X11 graphics 
device under linux?

I thought that the page-up/page-down keys were supposed to do the trick, 
but the frame (window) seems to be kind of immune to any kind of keyboard 
input. The only reaction I ever see is that the mouse pointer changes to a 
"+" when moved into the frame.

I issue these commands:

-- QUOTE START

Which produces the following frame:




Is it necessary to initialize the graphics device so that old pages are 
stored and accessible for paging? Or am I just pressing the wrong buttons.

Any input is appreciated! Please let me know if further info re. 
versions/installed packages/etc is needed.

Thanks, PMD.

It is baffling, rather than easy.  What did you find in your homework that 
told you that the X11() device had 'pages' and responded to those keys?

I am unaware of any documentation that says otherwise, so please enlighten 
us with the fruits of your researches.

The windows() device has this capability, but it is not enabled by 
default.  I don't believe any of the third-party graphics devices in 
CRAN package do.
