summary.fdata.comp: Correlation for functional data by Principal Component Analysis

Description

Compute correlation principal components of functional data and scalar response y.

Usage

# S3 method for fdata.comp
summary(object, y = NULL, biplot = TRUE, corplot = FALSE, ...)

Arguments

object

fdata.comp class object calculated by: fdata2pc, fdata2pls, fregre.pc or fregre.pls.

y

(optional) The argument is only necessary if corplot=TRUE.

biplot

=TRUE draw the biplot and PC (or PLS) components.

corplot

=TRUE draw correlations between y and PC (or PLS) components.

…

Further arguments passed to or from other methods.

Value

If corplot=TRUE, are displaying the biplot between the PC (or PLS) components. If corplot=TRUE, are displaying the correlations between the PC (or PLS) components and response y. If ask=TRUE, draw each graph in a window, waiting to confirm the change of page with a click of the mouse or pressing ENTER. If ask=FALSE draw graphs in one window.
