dev.off()
Notice how the canvas' margins are relatively far from the plotting
area.

First I tried your code:
> Cairo("example.pdf",
type="pdf",width=12,height=12,units="cm",dpi=300)
Error: could not find function "Cairo"
Then I tried:
> cairo_pdf("example.pdf",
type="pdf",width=12,height=12,units="cm",dpi=300)
Error in cairo_pdf("example.pdf", type = "pdf", width = 12, height =
12, :
unused argument(s) (type = "pdf", units = "cm", dpi = 300)
So I guess someone with your as yet unstated OS can take over now.
