Quantile-quantile plot
----------------------

    ^qqplot2^ varname1 varname2 [^if^ exp] [^in^ range]
    [^,^ graph_options ]


Description
-----------

^qqplot2^ plots the quantiles of varname1 against the quantiles of
varname2.


Remarks
-------

^qqplot2^ minutely generalises ^qqplot^ in the sense that the user can
control the main title through the ^title()^ option.


Options
-------

graph_options are options allowed with ^graph, twoway^, apart from
        ^symbol( )^, ^connect( )^ and ^sort^. Note that the ^title( )^
        defaults to "     Quantile-Quantile Plot". As a special case,
        ^title(.)^ blanks out the title.


Examples
--------

        . ^qqplot2 length width, ti(Length and width)^
        . ^qqplot2 length width, ti(.)^
