According to the help file for the boxplot function, default whiskers are
drawn to the nearest value not beyond a standard span from the quartiles,
where the standard span is defined as 1.5*(Inter-Quartile Range). Is there
an argument for this function that will enable the ends of the whiskers to
be located at the 2.5th and 97.5th centiles?

Thank you
