R Documentation

Plotting scores of principal component analysis of density functions

Description

Applies to an object of class fpcad (see details of the fpcad function). Plots the scores.

Usage

## S3 method for class 'fpcad'
plot(x, nscore = 1:3, sub.title = NULL, fontsize.points = 1.5, ...)

Arguments

`x`	object of class `fpcad` (returned by `fpcad`).
`nscore`	numeric vector. The numbers of the score vectors to be plotted. Warning: Its components cannot be greater than the `nb.factors` argument in the call of the `fpcad` function.
`sub.title`	string. Subtitle to be added to each graph.
`fontsize.points`	Numeric. Expansion of the characters (or symbols) of the groups on the graph. This works as a multiple of `par("cex")` (see `points`).
`...`	optional arguments to `plot` methods.

Details

Plots the principal scores returned by the fpcad function. A new graphics window is opened for each pair of principal axes defined by the nscore argument.
