R help - Feb 2005 - Could anyone answer for the following question

Hello , 
could anyone answer for the following question for me:
 
 
I am using R 2.0.1 under Windows XP. I want to write a function that 
makes four graphs and stores each of them in graphics history. When the 
function finishes, in other words, I want its graphical output to be 
stored in a way that I can look at it using PgUp and PgDn. I think I need 
commands I can put in a function that

--clear graphics history
--either turn on graphics history recording or store the current graph

Can anyone explain how to do this?


Thank you so much

options(graphics.record=TRUE) turns on graphics recording.
This can also be done from the History menu of the graphics window.

All subsequent plots to the graphics device will be saved.

windows(record = TRUE) will turn on windows graphics history and savePlot will
save a windows plot in a file.   You can also turn it on manually by
clicking on the graphics window and making sure History | Record is 
checked.

(Its also possible to save the low level graphics that R displays
using the displaylist and you can search r-help for more info
on 'displaylist' but I don't think that is what you are looking
for.)
