plotscores {fda}

Plot Principal Component Scores

Description

The coefficients multiplying the harmonics or principal component functions are plotted as points.

Usage

plotscores(pcafd, scores=c(1, 2), xlab=NULL, ylab=NULL,
           loc=1, matplt2=FALSE, ...)

Arguments

pcafd

an object of the "pca.fd" class that is output by function pca.fd.

scores

the indices of the harmonics for which coefficients are plotted.

xlab

a label for the horizontal axis.

ylab

a label for the vertical axis.

loc

an integer: if loc >0, you can then click on the plot in loc places and you'll get plots of the functions with these values of the principal component coefficients.

matplt2

a logical value: if TRUE, the curves are plotted on the same plot; otherwise, they are plotted separately.

...

additional plotting arguments used in function plot.

Side Effects

a plot of scores
