help.search("cov.mve")  gives

cov.rob(MASS)           Resistant Estimation of Multivariate Location
                         and Scatter

so you see not to know how to search.

R is not a clone of S-PLUS (sic), but a different system based on the S 
language.  Often there is better functionality in R (and indeed in this 
case there is later enhanced functionality in S-PLUS too).
