creating PNG plots on the linux terminal

I have an R script that I run on a linux server (Debian Wheezy 7.7). This script is meant to do some computations and generate plots into PNGs. Unfortunatelly I get an error:

> savePlot("myplot", "png")
Error in savePlot("myplot", "png") :
  can only copy from 'X11(type="*cairo")' devices

How do I get around this? I am only connected from Win XP with PuTTy, I don't have any X-windows set up on my XP and I don't want to bother with this - all I need is to run the script and produce the PNGs. Thanks!

On my Ubuntu distribution, calling x11() before plot() resolved this issue. This blog post gives more details on different operating systems.

You may have more luck calling the device internally:

png("plot.png")
    plot(1)
dev.off()

If you don't want to bother with opening an instance of R, you could save the above script (e.g. "script.01.R") and run the following from the console:

R CMD BATCH script.01.R

This should also work to create the .png.
