Copy it to PNG and find a licensed conversion program from PNG to GIF.
(Recall that writing the GIF format is encumbered by patent claims in some
countries: the relevant patent has expired in the US but not yet in the EU
nor in Japan.)

If your port of R does not have png(), use bitmap().

BTW, it really does help to know your OS when answering such questions.
