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
.
