I've known people who set values to NA that are outside some predefined threshold such as less than the .05th percentile (the .0005th quantile) and the 99.95th percentile at the high end. I'm not so eager to "erase" values at either end, but there would be automated ways of doing that on a copy of the data. Post a better description of the data problem.
