[R] Saving plots as byte streams

[Richard.Cotton at hsl.gov.uk]

Is it possible to save plots as byte streams?  For example, if I want the 
bytes for a PNG plot, I could use

#Write the plot to a PNG file
png("test.png")
plot(1:10)
dev.off()

#Read the bytes back in from the file
plotbytes <- readBin("test.png", "raw", n=2000)

Ideally, I'd like to avoid having to bother writing to the file in the 
first place, and simply store the bytes in a variable.  How do I do this?

Regards,
Richie.
