I'm trying lmrob, cor.mve and cor.mcd in R for robust correlation of two number series (of the same length) A and B. I get different results if I put A~B or A,B than if I put B~A, or B,A. Might someone guide me as to why? thanks

From the help files, lmrob fits a regression model which is not the same as correlation. I would expect lm(A~B) to be different from lm(B~A). In which package is cor.mve and cor.mcd? – Andrie May 3 '11 at 7:48
Did you mean cov.mve and cov.mcd in package MASS? – Andrie May 3 '11 at 8:01
