Summary of a Principal Components Object

DESCRIPTION:

Produces a summary that shows the importance of the components, and optionally some or all of the loadings.

USAGE:

summary.princomp(object, loadings=F, cutoff=.1) 
summary.bdPrincomp(object, loadings=F, cutoff=.1) 

REQUIRED ARGUMENTS:

object
an object of class "princomp" or "bdPrincomp".

OPTIONAL ARGUMENTS:

loadings
a logical value or a number stating the number of components for which loadings will be given. If loadings is FALSE, then no loadings will be given.
cutoff
a number giving the cutoff for printing the loadings (see print.loadings).

VALUE:

an object of class "summary.princomp" having components:
varmat
a matrix with rows containing the standard deviations of the components, the proportion of variance, and the cumulative proportion of variance.
loadings
part or all of the loadings matrix of object. This may be NULL depending on the value of the loadings argument.
cutoff
the input value of cutoff.

DETAILS:

This is the "princomp" method for the generic function summary.
