[R] interrupted Y axis

I did not find an answer to my question after a quick
search using the R
search engine so thought I'd ask away:

Does any know if there's a function exists to create
an interrupted Y axis?
What I mean by interrupted Y axis is that part of the
Y axis has been
removed or excised to permit one to see parts of the
data in more detail.

Perhaps an example will make this clear. Please go to
http://www.jbc.org/cgi/reprint/274/41/28950 and open
the PDF document
located there. Go to page 4, figure 2c provides a
crude example of what I
mean by interrupted Y axis. Part of the Y axis between
800 and 4500 has been
removed to permit easy inspection of the upper end of
the range of data.
(This is not my work but simply an example of what I'm
trying to describe.)
One finds these interrupted Y axis graphs in
newspapers or other
periodicals, more often than not as a bar chart.

Does a function in R exist to permit on to this easily
to a graph? If not,
would such a function be useful? If yes, would the
grid package be the right
tool for me to try and implement this?
