nineplot 

Normal quantile plot with reference plots 
 DESCRIPTION
 Produces a normal quantile plot with surrounding plots of
pseudonormal random numbers for reference.

 USAGE
 nineplot(x)

 REQUIRED ARGUMENTS
 x  a numeric vector

 DETAILS
 It is difficult to calibrate standalone normal quantile
plots without a great deal of experience. In this plot,
the normal quantile plot for the sample in question is
positioned in the middle of the plot, with eight randomly
generated plots for reference. If the sample appears the
least normal of the nine plots, then it is nonnormal
with Pvalue about 0.11.
The nineplot follows an idea
of Peter Lewis and Bill Kemple.
 EXAMPLES
 x < rt(20,4)
