labelcex=1,lineht=NULL,showall=TRUE,Nwidths=FALSE,barlabels=NULL,
showlabels=TRUE,arrow.cap=NA)One level of the breakdown produced by brkdnNest.
The left and right x coordinates for the bar or group of bars to be displayed.
The proportion to shrink the width of the bars at each level.
Whether to display error bars on the bars.
Whether to use offsets or absolute values when displaying measures of dispersion.
The colors to use to fill the bars. See Details.
Character size for the group labels.
The height of a margin line in user units.
Whether to display the bars at any levels above the last.
Whether to scale the widths of the bars to the number of observations.
Optional labels to display below the bars.
Whether to display the labels below the bars.
The width of the "cap" on error bars in user units, defaulting to 0.01 of the width of the plot.

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.
