[R] Change the limits of a plot "a posteriori"

Hi all

How can I change the limits (xlim or ylim) in a plot that has been already

For example, consider this naive example 

When adding the second curve, it goes off the original limits computed by R
for the first graph, which are roughly, c(0,2.1)

I know two obvious solutions for this, which are:
1) passing a sufficiently large parameter e.g. ylim=c(0,4) to the first


2) switch the order in which I plot the curves

but I guess if there is any way of adjusting the limits of the graphic "a
posteriori", once you have a plot with the undesired limits, forcing R to
redraw it with the new limits, but without having to execute again the
"curve" commands

Hope I made myself clear

Best regards and thank you very much in advance
