Use
mat <- eig[["vectors"]]
If x is a list, ``x[i]'' gives you a (sub-) list of length 1,
whereas ``x[[i]]'' gives you the single element of that list.
A possibly subtle but important distinction.

Hi
I need to extract the data returned by Eigen to plot the eigenvectors.
However, when I try and eigv = eigen(covariance); it returns an object with
the matrices containing eigenvalues and vectors.. how can I extract the
eigenvector matrix from this??
When I try mat = eig["vectors"] it returns a
