Your R session has obviously x11() as the default plotting device
... e.g.,
plot(1:10)
at the prompt should also give an error, if no graphics device is
open. I don't know too much about MacOS X, but having the DISPLAY
variable set without having an X11 server surely means asking for
trouble on Linux, and I guess MacOS X is not different ...
