y-axis with "break"

Dear R-users

I would like to draw a barplot with a special y-axis. Most of my data points are 
in the range from -50 to 50, apart from one value that is 550. I would now like 
to have a y-axis from -50 to 50, then a "break" and the "rest" of the y-axis, 
let's say from 500 to 600. In order to make clear what I'm trying to do, I 
attached a figure.

Is it possible to do this in R?

Thanks for your help

Nick
