I am looking for a function to restore saved graphics for further editing, such as changing its title, labels, or legend. How can I do it in R? Thanks in advance. -- Daehyok Shin (Peter) Geography Department Univ. of North Carolina-Chapel Hill

Thanks in advance.Probably the easiest way is simply to save the code that you used to make the graphic, edit the code, and run it again. This is a good way to work with R anyway. If, for some reason, the graphics tools available for R are not sufficient - and I find this hard to imagine - you can also save graphics as xfig files and then edit them with xfig, assuming that you are using Unix/Linux.

Is it so difficult to develop a function or an object to generate all the
code automatically in R?

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") Shin <sdhyok <at> email.unc.edu> writes: : : I am looking for a function to restore saved graphics for further : editing, such as changing its title, labels, or legend. : How can I do it in R?

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.
