FWIW, there is a way to have one or more scrolled graphics devices
using the RGtk (www.omegahat.org/RGtk) and gtkDevice (from CRAN)
packages. This currently works only on Unix/Linux.
The following code creates a window with a graphics device inside a
scrolled window inside a top-level Gtk window.
library(RGtk)
library(gtkDevice)
win = gtkWindow(show = FALSE)
sw = gtkScrolledWindow()
scrolledDevice <- gtkDrawingArea()
scrolledDevice$SetUsize(5000, 5000) # pixels
sw$AddWithViewport(scrolledDevice)
win$Add(sw)
win$SetUsize(800, 700) # pixels
win$Show()
asGtkDevice(scrolledDevice) # (from gtkDevice)
Now you are ready to plot.
plot(rnorm(1))
