R4-G9: Female? Edit

I do not remember any source calling R4-G9 or the Azure Angel droid female. Can someone please tell me where they state this fact?

R-series astromechs with masculine programming speak Binary in the form of beeps and whistles, whereas those with feminine programming speak it in the form of electronic clucking. ZeldaTheSwordsman 04:52, 16 November 2008 (UTC)
