morph.PC: Plots the morphological space along PC axis.

Description

Given a matrix of harmonic coefficients, a Nef-object, calculates and plots morphological space i.e. reconstructed shapes using and distributed on the orthonormal set defined by Principal Component axes.

Usage

morph.PC(Nef, sd.nb=1, pca.ax=seq(1, 3))

Arguments

Nef

the Nef object

sd.nb

a numeric given the number of standard deviation to represent shape deviation along each PC axis

pca.ax

a numeric or a vector of numeric indicating on which Principal Component to display variation

Examples

data(bottles.nef)
morph.PC(bottles.nef)
morph.PC(bottles.nef, 2, 1:3)
