How do you graph data when you have lots of small values but few extremely large values?

I was thinking of splitting the y-axis into two? Is this possible?

Shane,

   Does a boxplot show what you want to display? If not, what information do
you wish to convey about these data?

Look at the plotrix package and see:

The plotrix package provides a way to insert a break into a y-axis but doing so is not considered really good plotting behaviour.  The split axis method actually shows the data but human perception has a hard time handling the split.

I'd look at some kind of transformation as a possibility or pehaps plotting two graphs or panels (see http://stats.stackexchange.com/questions/1764/what-are-alternatives-to-broken-axes).
