I want to get the loadings of components from pcaMethods.

To illustrate the problem, I have a matrix x

By loadings(x), I get

However, I want to get

Anyone knows how to do that?

Thanks a lot!

It is conventional for high-throughput data to have samples in columns and reporters (genes, transcripts, whatever) in rows. In which case, when you get the loadings, what you should expect to get is the thing you get. What you want is (apparently) to get the loadings by gene, which doesn't make any sense - PCA is intended to collapse the gene information, so by definition you don't have anything by gene any more, because you have collapsed the data into linear combinations of the underlying gene expresssion.
