The jpeg() command should *replace* the windows() command. They both open new graphics devices. One problem you'll have is that jpeg takes dimensions in pixels by default; if you want to express it in inches, you need to say so, and also say what resolution you're assuming. For example, jpeg(filename="myplot.jpg",quality=100,width=6.25, height = 3.75, units="in",res=96) for 96 dpi resolution.
