Hi, I am a new R user and am currently using princomp to conduct a PCA. 
I have read the help(princomp) and still do not quite understand 
everything in the help. Basically I want to get the covariance matrix, 
and eigenvector/eigenvalues (loadings()?) so that I can find the 
principle components. Thanks!
