You can use merge but to do so you will need to define the common key first. This can be a rowname in the case of a matrix or names in the case of a vector. v1 - 1:10 names(v1) - LETTERS[1:10] v2 - 101:105 names(v2) - sample( LETTERS[1:10], 5 ) merge( v1, v2, by=0, all=TRUE ) Row.names x

(R 2.0.1) summary() gives the correct results. The print.loadings() print method is just giving the squared length of each of the eigenvectors, which is 1 by definition, of course. I don't know whether this is a bug or intentional, but it certainly seems silly. In general, it is good practice
