I consider bwplot to already provide a grouped display (box plots are univariate summaries, and bwplot allows you to display several of them together within a panel). What you are looking for may be appropriate in certain situations, but is not general enough to warrant a built-in implementation. In other words, you'll have to write your own panel function. > I thought I'd find something about this in the archives, but I'm > either not using the right keywords or the question hasn't come up > yet.
