Hello Charles,

A little over a year ago I wrote a function to do this in response to a
tech support query.  This function has recently gone up in the Technical
Support branch of our home page.

The Technical Support FAQ is at

and the NormalProbabilityPlot function is at

It's no full-fledged package since it was just a response to a query,
but it is a useful little function and might give a direction to go in
if you need more sophisticated things.

I recommend browsing the Technical Support FAQ in general while you're

Best regards,
