In a batch script (i.e. there is no screen device), I would like to create both
a PDF file and a PNG file from the same plot. I thought this would be the way
to do it, but it isn't:
R> bitmap("copy.png", "png16m", res=300)
R> pdf("copy.pdf")
R> plot(1:10, 1:10) # Plot into pdf file
R> dev.copy(which=2) # Copy to png file
R> dev.off(3) # Close pdf
R> dev.off(2) # Close png
The PDF comes out fine, but the PNG appears blank. Any ideas what I'm doing
wrong? TIA.
