\begin{Description}\relax
The \code{\Link{summary}} method for class \code{"princomp"}.
\end{Description}
\begin{Usage}
\begin{verbatim}
## S3 method for class 'princomp':
summary(object, loadings = FALSE, cutoff = 0.1, ...)

## S3 method for class 'summary.princomp':
print(x, digits = 3, loadings = x$print.loadings,
      cutoff = x$cutoff, ...)
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{object}] an object of class \code{"princomp"}, as
from \code{princomp()}.
\item[\code{loadings}] logical. Should loadings be included?
\item[\code{cutoff}] numeric. Loadings below this cutoff in absolute value
are shown as blank in the output.
\item[\code{x}] an object of class "summary.princomp".
\item[\code{digits}] the number of significant digits to be used in listing
loadings.
\item[\code{...}] arguments to be passed to or from other methods.
