Warning: untested code ahead

I think it would look something like this:

  ## a graphNEL instance you want to plot
  ## setup the postscript device.  All plot commands will be 
  ## sent to this device until you call dev.off().  
  postscript(file="bigGraphPlot.ps", paper="special",
             width=15, height=15)
  ## do the plot, you should not see anything on screen
  ## close the graphics device

You might also want to try the pdf() device.
