Details

drawNestedBars displays the bars for the nested breakdown performed by brkdnNest. It starts at the top of the list and calls itself for each level of the breakdown. It is unlikely to be useful for anything else.

The combination of showlabels=TRUE and showall=FALSE allows the display of all of the labels below the plot with only the last set of bars being displayed. To have a set of labels not displayed, pass explicit barlabels and have zero length labels for the level that is not to have labels.
