The eigenvectors in pca object: row or column arranged?

[xwind]

Hi,

Maybe a silly questions.

I generate the pca object through :

    pc <- pca.xyz(xyz[, ca.inds$xyz])

So the eigenvectors in pc$U is row arranged or the column arranged? In other words, whether the column is a eigenvectors? (or the row?)

I want to confirm it to extract the eigenvectors in each domain in PC1s.

Should be column arranged.

Thanks very much ...
