[R] How I assign the result of a plot to a variable?

[Ajay Askoolum]

I can write a plot to a files of a given format using this:

x-sample(c(1:100),10)
bmp(c:/mygraph.bmp)
plot(x)
dev.off()

and then show the image file in another application. This application can also 
display the image from the stream of numbers that define the image.

How I can get the plot as a stream of numbers?

Try this,

plot(1:10)
img - grid::grid.cap()
# grid.raster(img)
stream - col2rgb(img)
write.table(stream, file=dam.txt, row.names = FALSE,
col.names = FALSE)

(you'll have to restore the dimensions of the matrix once you've read
the rgb values for each pixel)
