Share:

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.
