You could try creating a PNG with bitmap() using a high resolution, e.g.,

bitmap("test.png", type = "png256", res = 1200) plot(1:10, rnorm(10))
dev.off()

Preview can read the resulting PNG file just fine and the Windows version of Office can insert PNGs, displays them well, and allows resizing. (I don't have an OS X version of Office so can't test that the OS X version would handle the PNGs equally well but I would have to assume it does.)

bitmap() requires Ghostscript which I have installed on my system in /usr/local/bin. I'm not sure whether Ghostscript came with OS X or if I installed it myself but it's freely available.

Hope this helps,

Stephen
