Save R Cairo graphics on windows

I've just found out that I can get antialiased R graphics on Windows via Cairo so I've installed the package right away. Unfortunately, though, I'm stuck trying to save the output. I can't seem to copy it and right click doesn't do anything.

Ideas?

The Cairo functions are now included in most R distributions. All you need to do is just specify type="cairo":

png(filename="fn.png", 
    type="cairo",
    units="in", 
    width=5, 
    height=4, 
    pointsize=12, 
    res=96)
...
dev.off()

I wrote a blog-post about the Cairo packages and found out about the new feature through a comment :-)

This should work (it does for me using R 2.14 under linux):

cairo_pdf("spam.pdf")
plot(1:10)
dev.off()

and the resulting pdf is in the current work directory. Alternatively, when having the cairo package installed, you can use:

CairoPDF("spam.pdf")
plot(1:10)
dev.off()

to get the same effect.
