nineplot function

produces a Normality plot for the argument surrounded by eight other Normality plots for Normal distributions having the same mean and standard deviation as the argument

Normality plots can be hard to judge if one is not experienced. This function plots a Normality plot for the data surrounded by eight other Normality plots for samples with the same mean and standard deviation that were randomly generated. The eight plots provide an idea of the variability to be expected in Normally distributed data.
