If you use r.stats to find the outliers you could reclass
the map to eliminate the outliers, then use r.rescale on
the map without the outliers.
|The discussion of reclass and rescale prompts me to ask
|a question I have had for awhile.  Is there an easy way
|to reclass into deciles or quartiles or whatever, where
|10% (or 25%) of the values fall into each of the new 
|categories?  Rescale operates on the data range, so extreme
|values may result in a category with a large range but with
|very few cell values actually falling in it.
