It it just a coincident that it appear that recordPlot()/replayPlot() only works for grDevices::deviceIsInteractive() graphics devices? If not, should ?recordPlot clarify that "These functions record and replay the displaylist of the current [interactive] graphics device."? Q. ...or is just the fact that currently png(), pdf() etc. won't populate "the displaylist" (whatever that is), bu...
