Removing Outliers Function

For your number 2, look at the outliers data set in the TeachingDemos package and run the 1st set of examples, yes it uses a different rule than you use, but still a common one.  Think about what is happening in the example, doesn't that make you a little nervous about methods that automatically discard "outliers"?
