Is there a way to open a graphics device that plots entirely to an array
or raster in memory? I'd prefer it to use base graphics, but grid would
be fine if it makes a difference.
For an explicit example, I'd like to do the equivalent of this:
filename <- tempfile(fileext = ".png")
png(filename)
plot(1:10, 1:10)
dev.off()
library(png)
img <- readPNG(filename)
unlink(filename)
which puts the desired plot into the array `img`, but I'd like to do it
without needing the `png` package or the temporary file.
A possibly slightly simpler request would be to do this only for
plotting text, i.e. I'd like to rasterize some text into an array.
