Summary Method for Principal Components Models

DESCRIPTION:

Returns a summary of the principal components models stored in a fit.models object with virtual class pcompfm.

USAGE:

summary.pcompfm(object, loadings=T, cutoff=0.1, ...)

REQUIRED ARGUMENTS:

object
a fit.models object with virtual class pcompfm that contains the fitted models.

OPTIONAL ARGUMENTS:

loadings
if TRUE, the loadings are included in the summary.
cutoff
the cutoff value used by print.loadings. Entries smaller than cutoff are not printed.

VALUE:

a summary.pcompfm object with the following components:
mod.names
the names of the models in object.
calls
a list containing the call of each model in object.
qvar
a matrix with one row for each model in object. The columns contain the cumulative sum of the fraction of the variance attributed to each component.
pvar
a matrix with one row for each model in object. The columns contain the fraction of the variance attributed to each component.
sdev
a matrix with one row for each model in object. The columns contain the standard deviation of each component.
loadings
if loadings = T, a list containing the loadings for each model in object.
cutoff
the cutoff specified in the call, by default 0.1.
