One of the data sets I deal with is quite strange. The datawarehouse I downloaded the data from has a lot 999999999 values in one of the variables. Apparently the computer system on which the datawarehouse sits on does not support storing of null values. So they use 999999999 as the "null" value. Now if I just run `pretty` in R on the variable, it gives non-sensical ranges. 

* Is there a package with a version of `pretty` that can deal with outliers by putting them in the range of say (100,High) ?
