        bxp(z, width, varwidth=FALSE, notch=FALSE, ...)

   AArrgguummeennttss::

          z: a list containing data summaries to be used in
             constructing the plots.  These are usually the
             result of a call to `boxplot', but can be gener-
             ated in any fashion.

      width: a vector giving the relative widths of the boxes
             making up the plot.

   varwidth: if `varwidth' is `TRUE', the boxes are drawn with
             widths proportional to the square-roots of the
             number of observations in the groups.

      notch: if `notch' is `TRUE', a notch is drawn in each
             side of the boxes.  If the notches of two plots do
             not overlap then the medians are significantly
             different at the 5 percent level.

        ...: Graphical parameters can be passed as arguments to
             this function.

   VVaalluuee::

        This function is invoked for its side effect which is
        to draw box plots based on the given summaries.  It is
        usually called from `boxplot', abut can be invoked
        directly.
