[R] Plotting Long Time Series

I have some time series data which I am interested in plotting. The standard function for plotting ts, or zoo objects work fine, however, I am curious about plotting long time series with a dynamic aspect ratio. My point is this, say I have a time series of 4000 observations, so the image width is x units and height is y units. Now after updating my data, my time series has 6000 observations. The way plots happen are, the image fits to the screen, or a standard aspect ratio I assume. Can I have the plot then change to 1.5x units wide and y units high?

Perhaps a visual analogy would be: a electrocardiogram which prints out of an ecg machine. the pulses are plotting on one damn long paper :)
