Hello. First post, please excuse lack of experience.
I recently switched from MS-Win to Kubuntu and find it rather difficult
to recover Cran-R ease of use.
The "Graphics history" facility available under Windows was, for me,
extremely useful.
From Murrell's 2005 book (see citation below) I understand that no
such
facility is available under non-Windows systems.
In R-help archive, a 2000 comment from Ripley seems to confirm. (see
below)
Questions:
- do I correctly understand that "No<Graphics history> facility is
available for Linux systems"?
- (if Yes above) Please, let me understand why??
Many thanks for sharing.
Sincerely, Roberto Scotti

"1.3.2 Multiple pages of output"
"For a screen device, starting a new page involves clearing the window
before
producing more output. On Windows there is a facility for returning to
previous
screens of output (see the \History" menu, which is available when a
graphics window has focus), but on most screen devices, the output of
previous
pages is lost."

Crucially, you did not say you were doing this on Windows, and it is
only
available on the windows() device on Windows. I am not aware of any
way to
do this.
Scott,
I am not aware of anything that replicates the "record graphics
history" in Ubuntu. However, there are some tools/tricks that can be
helpful.
1. If you run an .R file in batch mode (R CMD BATCH foo.R), any plots
the code creates will be collected in the "Rplots.pdf" file. You can
then use any pdf viewer to view the plots.
2. If you want to save a specific plot, try 'foo <- recordPlot()'.
That will save the plot to 'foo'. To view the plot again,
'replayPlot(foo)'.
3. If you are using R interactively, if you enter the command
'pdf("Rplots.pdf")', any plot you create will be written to that file.
The downside is that the plot will not be shown on the screen.
However, if you open that pdf file, you can view the contents of the
file as it is being updated. So, as I work in a window and create a
new plot, it is appended to the pdf file and shows up a second later
in the pdf viewer. You can then page through the plots. Kind of a
hack, put it works.
I don't think there is a way to easily plot to multiple devices, say a
pdf and a X11, at the same time. There is a function plotf in the
agesmisc package that appears to do this, but I haven't played with it.
Hope this helps,
Michael
