Try:

?cov.rob
Search on the R site ought to show you. cov.rob() is in MASS (part of the

rrcov package with the covMcd() function.

Hello everyone! I'm having the dreaded repeated rows problem in RODBC.

I think the issue here is in the two keywords - permutations or sample.
AFAIK, permutations should return all admissible (by some rule)
combinations. If this is a large number, as some have pointed out, then
one essentially takes a _sample_ of all admissible combinations. Since
