And so does every other graphics device.  Note though that the 
height/width of the device is not that of a plot (nor necessarily of the 
figure): see the graphics pars 'pin' and 'fin' if you really want to 
specify the plot or figure size (as in the subject line).

`An Introduction to R' explains this in more detail'.
