| \title{Summary method for Principal Components Analysis} |
| \usage{ |
| \method{summary}{princomp}(object, loadings = FALSE, cutoff = 0.1, \dots) |
| |
| \method{print}{summary.princomp}(x, digits = 3, loadings = x$print.loadings, |
| cutoff = x$cutoff, \dots) |
| } |
| \arguments{ |
| \item{object}{an object of class \code{"princomp"}, as |
| from \code{princomp()}.} |
| \item{loadings}{logical. Should loadings be included?} |
| \item{cutoff}{numeric. Loadings below this cutoff in absolute value |
| are shown as blank in the output.} |
| \item{x}{an object of class "summary.princomp".} |
| \item{digits}{the number of significant digits to be used in listing |
| loadings.} |
| \item{\dots}{arguments to be passed to or from other methods.} |
