[R] Plot zooming i.e. changing ylim according to xlim

Dear R-gurus,

I would like to zoom in a plot, e.g. I select a region on the x-axis and 
then I would like the ranges on the y-axis to change accordingly.

Is it possible to do this with existing functions, or do I have to 
invent some data selection before plotting?

See below a short example, where I select ylim with trial and error, 
which I want to avoid.

Cheers, Henrik Andersson
## Example -- in reality more numbers, no function
x <- seq(0,20)
y <- exp(-x)


## Zoom in the end, to see what's happenning


## Try other ylim


## Not enough


## Better
