If you insist ...
1. You are reinventing wheels (poorly).
RSiteSearch("outlier tests",restr="fun")
##RsiteSearch is a handy interface to search facilities on CRAN.

will show you that a R package, outlier, already exists that does all
the tests you can imagine -- and more.
2. For why this is a BAD idea, you would need to read up on the
voluminous literature. Talking to a local statistician might be a
better alternative. But here's a hint: AFAIK, the FDA allows no such
tests in the submissions of clinical trial data because it would bias
the results. (Correction welcome if this statement is wrong).
Cheers,
Bert
