I know how to set graphic parameters by calling par(), but what I'd like is a way to set the default values so that subsequent calls to par() use my defaults. The reason to want this is that every time I create a new graphic window (I'm using quartz on OSX, and so far no answers in the Mac mailing list), my parameters get reset to the builtin defaults. I read about the "unexported variable .Pars," but would like to know if there's any way to manipulate that variable. thanks Carl
One way that I do it is to save the default parameters with the
following statement in my profile:
assign('Default.par', par(no.readonly=T))
An then I have a function which will reset them:
plotReset <-
function()
{ # reset plotting window
par(Default.par)
windows(width=7.5,height=4.7, record=T, pointsize=10)
}

What is the problem you are trying to solve?
Write a function that opens a new graphics window (quartz in your case) then changes the parameters to what you want as the default. Then any time you want/need a new graphics window, call your function. Also look at ?options and scroll down to 'device' and ?Startup Hope this helps, -- Gregory (Greg) L.
