Did the MASS package disappear? Specifically, I'm looking for a function to find the MCD (robust measure of shape and location) for a multi-dimensional data matrix. Anyone know anything about this?

Search on the R site ought to show you. cov.rob() is in MASS (part of the `VR' bundle, and should be part of all R distribution). There's also the rrcov package with the covMcd() function.
