R help - Mar 2007 - Recalling and printing multiple graphs. Is there something in the HISTORY menu that will help?

I have written an R function that produces multiple graphs. I use
par(ask=TRUE) to allow for the inspection of each graph before the next
graph is drawn. I am looking for a way to recall all graphs drawn in an
R session, and a method that can be used to print all the graphs at one
time. I know that I could simply print each graph after I inspect the
graph, but this gets tiresome if one's function produces tens of graphs.
I suspect that if I knew more about the history menu (which currently
has an entry RECORDING) I could get the graphs to be replayed and
printed, but alas I have not been able to find instructions for using
the HISTORY menu. Please take pity on my  when you let me know that some
easy search or command could get me the information I needed. I have
looked, but clearly in the wrong places.

?win.metafile and ?replayPlot might allow you to "replay" the saved
plot
history (by default in .SavedPlots) into a file in emf or wmf format, I
think, but I haven't actually tried this -- don't know if it will work
for
multiple graphs.

Let us know if this approach works if you don't get a definitive answer
elsewhere.

PLEASE do read the posting guide http://www.R-project.org/posting-guide.html
and provide commented, minimal, self-contained, reproducible code.

options(graphics.record=TRUE)
can be used to switch the recording on (MS Windows, not sure about other 
platforms). See ?options
To set this option as default, use .Rprofile

It is however quite annoying to examine and save all the graphs 
manually... You might find functions like postscript(), png(), jpeg() 
and others useful.

Here is a function that I have used to write the files on my Windows
machine.  I put this function call after each graph that I produce and it
will write out a new file and tell me what the file name is.  I can then go
back and copy the files into a document or a PowerPoint presentation.


f.plot <- local({
    # PlotNumber is 'local' to the function
    PlotNumber <- 1 # initialize the plot number
    function(){   # return the function
      myplot <- sprintf("ws.%03d.wmf", PlotNumber)
      dev.copy(win.metafile, file=myplot, width=10, height=7)
      PlotNumber <<- PlotNumber + 1  # increment for next plot
      cat("copied to:", myplot, "\n")
      invisible(dev.off())  # close the file
    }
})

At the end of each plotting sequence, just call "f.plot()" to save the
image.

I assume you are on Windows (please give OS and R version in
future help requests).  

The code I use before starting such functions is

graphics.off()
windows(record=TRUE)
.SavedPlots <- NULL

which closes existing graphics devices, opens a windows device
with recording on, and deletes any existing graphics history.

You can go through the history with PageUp and PageDown keys.

Within your function, you can call savePlot (q.v.) to save each
plot to a file just after it is generated.
