Dear R-Users, I am writing a package using S4 classes. In the generic method "plot" I want to set the title for the plotting window as I will have several windows and window titles help the users to distinguish the graphics without putting a title into the plot itself (this can be done by users whenever they want)
So I created a helper function .setDeviceTitle which I called after the plot has been done: ".setDeviceTitle" <- function(title = "title", dev = dev.cur()) { dev <- names(dev)[1] ## check for OS ## if (dev == "windows") { windows(title = title) } else if (dev == "X11") { X11(title = title) } else { quartz(title = title) } } The result is a new device with the title in addition to the old. Is it possible to give a window a title after the plot has been done? If not: Before I plot the device I cannot know what device it will be, so I thought about a check via capabilities(): if (any(names(capabilities()) == "X11")) { X11(title = title) } else if (any(names(capabilities)) == "windows") { windows(title = title) } else { quartz(title = title) } I want to have a safe method, which works on each OS R can run. How would you solve the problem?
