Saving plots as byte streams
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?

Richie.
