You will also have to create custom axis labels using axis(). However, the plotting function used in the paper you cite also breaks the bars that extend to the upper range (nice touch, wish I had thought of that). I'm not sure if any of the barplot* functions will do this out of the box. I would probably fake the bottom and top sections with homemade bars using rect() if I had this problem.

You might want to consider some of the approaches taken, including the axis.break() function in the 'plotrix' package on CRAN. Note however that the examples (ie. newspapers) you site are called Pop Charts by Bill Cleveland in his book The Elements of Graphing Data and are highly criticized. If you have such disparate ranges you might want to consider separate plots and/or log scaling. Be careful however, that expanding the vertical axis to isolate specific data can result in the visual perception of significant difference where none exists. This notion is also explored by Cleveland and Tufte (The Visual Display of Quantitative Information).
