They always apply to the current device only (and will create a current device if possible). > If you put a call to par in your startup script, then it will open a > graphics device and set the option, but if you close that graphics > device and do another plot then a new graphics device will be started > with the default parameters rather than what you set in the startup > script. > > You can set some of the options (including background color) when > starting a graphics device, that may be the better option. You can also set a hook (see ?setHook) on plot.new (see its help page), which could be used to set par(bg=). A hook on package grDevices would have avoided the reported error messages. (Calling graphics::par in startup code works in R-devel but not in 2.5.x, but using hooks works in any fairly recent R.) > There was some discussion a while back on having global options for some > of the graphics defaults, but I don't think anything has been > implemented yet. I don't believe there was agreement that was desirable. -- Brian D.
