If extreme values are known to be unreliable*, take a look at robust statisical
methods (or even the median) instead of the mean. huber in MASS and huberM in
robustbase are often appropriate for that kind of situation.
If the extreme values are not known to be unreliable, see previous posts...

*Reverence for data is fundamental, but that doesn't mean being blind to the
apparently limitless number of ways people, instruments and the universe at
large can foul up observations and data collection. A degree of scepticism
about extreme values is healthy; dogmatic retention or rejection is not.
