Re: [R] set par options once for entire R session
Hi Martin,
Depending upon what device parameters you want to set, you can write a
wrapper for the device call that includes the parameters:
my.x11<-function() {
x11(family="sans",font=2)
}
Then just call the wrapper instead of the device function. You could
make a little package with all of the devices you wish to use and just
load the package at the beginning of your R session.

Re: [R] set par options once for entire R session
The Details section of ?par starts of with:
"Each device has its own set of graphical parameters."
(So this is not Mac-specific.)
Strictly speaking, the options you set with par() are not "reset" when you
open a new graphics device. Rather, when a new device is opened, it is
initialized with default values of graphics parameters.
If you can find where those default values are stored (in a brief search I
did not find them), then perhaps you can change them at session startup
time.
I haven't tested this, but you might be able to make things a little more
convenient by defining a function
mypar <- function() par( {set whatever values you want} )
Then whenever you open a new device, immediately call that function:
pdf()
mypar()
plot(x,y)
dev.off()
png()
mypar()
plot(x,y)
dev.of()
And so on.

Re: [R] set par options once for entire R session
Martin: One simple approach: write your own graphics functions that are simple wrappers to the plot functions you use that set the par() values as you wish. You could even put them in a package that is loaded at startup. See ?Startup My understanding is that so long as a graphics device remains open, new plots on it will reuse the same par() settings. See,e.g. ?plot.new. Cheers, Bert Bert Gunter "Data is not information. Information is not knowledge.

[R] set par options once for entire R session
Hi, I would like to set plot-options via par() and keep them for all plots that are created thereafter. Currently after each plot device the parameters I can set with par() are reseted to their default value, at least on a Mac (R 3.2.1). Is there a way to define the parameters for plotting once at the beginning and then keep them for an entire R session?
