Hi,

The size of the plot is going to be largely dependent upon the output device being used and the dimension settings for the device. If you are going to use a bitmapped device (eg. png()) as opposed to a vector device (eg. pdf()), then the physical size of the image will also be dependent upon the resolution of the display (in pixels per inch) upon which the file is being viewed.

See ?Devices for more information on the available output devices on your system. Then select the particular device you wish to use for details on how to adjust the dimensions.

Regards,
