loadings(object, \dots)
loading.weights(object)
Yscores(object)
Yloadings(object)
Arguments
object
a fitted model to extract from.
...

Value
A matrix with scores or loadings.

Details
All functions extract the indicated matrix from the fitted model, and
will work with any object having a suitably named component.
The default scores and loadings methods also handle
prcomp objects (their scores and loadings components are called
x and rotation, resp.), and add an attribute
"explvar" with the variance explained by each component, if
this is available. (See explvar for details.)
