[R] How to restore and edit saved graphics?

[Shin, Daehyok]

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?

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

Thanks again.
