How to make a break on y-axis of a histogram chart using R?

Attached is a histogram chart with a break on y-axis which my friend made
for me using phot shop.  Do anyone know how to make such a break using R?
Thanks in advance.

Hi Hank,
As your illustration didn't make it through the R malware filter, I can 
only say that gap.plot in the plotrix package _might_ do what you want.
As Hadley has noted, make sure that it shows what you want to show.
