Create a 3 x 3 grid of quantile-quantile plots, the first of which corresponds
to the input data. The other eight plots arise from simulating random normal
data with the same mean, standard deviation, and length as the data. For use
in comparing known-normal qqplots to an observed qqplot to assess normality.

## Arguments

- sample
the variable to be plotted.

- data
data frame to use.

## Value

A 3 x 3 grid of qqplots.
