Minimal R plots

For my new business cards I wanted to impose data from an experiment onto the background of an image. For the best results I wanted to render the plot of data onto a transparent png without any axis, values or the standard box.

After a while I got to

> png(filename="transplot.png",width=900,height=400,bg="transparent")
> plot(timestamp[0:1000],snd_cwnd[0:1000],type="h",yaxt="n",xaxt="n",ann="F",frame.plot="F")
> dev.off()

Which generates the following image.
