Don't you get a popup error dialog? I do, and it says that
libgdk-win32-2.0-0.dll was not found. Only when I click on okay does it
return to the console to tell me about the cairoDevice failure. So I
think the real problem is with the libgdk not being present, and that
causes the cairoDevice dll to fail to load. Windows doesn't tell R
about the reason, it just says it failed.
The reason that library was not installed is that I didn't have RGtk2
installed properly. Try library(RGtk2), and make sure it works (and let
it install GTK if it wants), and things should be fine.
