Subject: [R] MASS mve_fits mycov.rob
Hello,
In R 3.0.1, I get the following warning that I do not get in R 2.15.3:
data(mtcars)
mycov.rob(mtcars[,1:3], method="mcd")
Error in .C("mve_fitlots", as.double(x), as.integer(n),
as.integer(p),? :
? "mve_fitlots" not available for .C() for package "MASS"
It seems like there was a change in MASS?? Can someone please help me
determine how to to use mycov.rob(x, method="mcd") in R 3.0.1 (I am
guessing that this includes anything that uses mve_fitlots...
Thanks.
