Default Panel and Prepanel Function for qqmath

Description:

     This is the default panel function for 'qqmath'.

Usage:

     panel.qqmath(x, f.value = NULL,
                  distribution = qnorm,
                  qtype = 7,
                  groups = NULL, ...)

Arguments:

       x: vector (typically numeric, coerced if not) of data values to
          be used in the panel. 

f.value, distribution: Defines how quantiles are calculated.  See
          'qqmath' for details. 

   qtype: The 'type' argument to be used in 'quantile' 

  groups: An optional grouping variable.  Within each panel, one Q-Q
          plot is produced for every level of this grouping variable,
          differentiated by different graphical parameters. 

     ...: further arguments, often graphical parameters. 

Details:

     Creates a Q-Q plot of the data and the theoretical distribution
     given by 'distribution'.  Note that most of the arguments
     controlling the display can be supplied directly to the high-level
     'qqmath' call.
