Thanks for the interesting solution. I am happy to find a way to save all graphic options into a file. There is a minor glitch. Is there is any way to replace title, not to overwrite it? And if I want to change the color of a line or the ranges of x or y axis, how can I do it with the restored plot?
The grid graphics package provides support for this sort of thing. If you have R 1.9.0 there are some vignettes describing grid and how to do this sort of thing in grid -- see vignette("grid") and vignette("interactive") for a start.
This may or may not be sufficient for your purposes right now -- grid doesn't give you any high-level plots and, although the lattice package does give you high-level plots, it doesn't make use of the bits of grid that would allow this sort of interaction just yet (we're working on it) -- so its immediate usefulness will depend on what you're trying to do.

Interestingly, there is no mention about dev.control() in the help document of recordPlot(). I think it should be there.
Thanks again.

Saving of the low level graphics that R displays can be 1. turned on with dev.control(displaylist="enable") and 2. turned off with dev.control(displaylist="inhibit"). recordPlot() can be used to save the display list in a variable.
For example:
# turn on display list, perform plot, turn off display list, add title # do not need next line if graphics device already active windows() # or x11() on unix dev.control(displaylist="enable") plot(1:10) myplot <- recordPlot() dev.control(displaylist="inhibit") title(main="My Title")
# now redisplay plot as it was before title and reissue title myplot title(main="My Other Title")
