Question

Such as margins, orientations and such…

dev.off() does not work for me. I am often using RStudio, with its inbuilt graphics device. I then have plotting functions, which I want to plot either in the default RStudio graphics device, or if I called X11(), before in a new window.

This behaviour doesn’t work with dev.off(). If my plotting function always calls dev.off(), it might inadvertently close the X11() window and instead plot in the RStudio device. If I always call dev.off() followed by X11(), it would always plot in a new window, even if I wanted to plot in the RStudio device.

Ordinarily that could be solved with getOption("device"), however, that always returns RStudioGD.

See ?par. The idea is that you save them as they are when you found them, and then restore:

old.par <- par(mar = c(0, 0, 0, 0))
## do plotting stuff with new settings

Now restore as they were before we changed mar:

par(old.par)
