It goes:  bwplot calls panel.bwplot, which calls boxplot.stats

help(boxplot.stats) 

gives you all you need to know, and more.

For the whiskers, check out the "coef" argument to boxplot.stats.  For
now, because of the way it's nested, you can only use the default of
1.5 with bwplot.  Sifting through the code, I don't see an easy, clean
fix for this, but I'm not a very good R programmer.
