Multivariate Analysis: manova.nef: Multivariate ANOVA on Nef objects

Description

A simple wrapper for Multivariate Analysis of Variance on the matrix of harmonic coefficients in a Nef object.

Usage

manova.nef(Nef, fac, retain=floor((nrow(Nef@coeff)-2)/4), drop=0)

Arguments

Nef

a Nef object.

fac

factor defining which groups of individuals to compare.

retain

numeric. The number of harmonics to retain.

drop

numeric. The number of harmonics to drop.

Value

• The MANOVA summary is printed.

Details

The number of harmonic coefficient can not be higher than the number of outlines ; you can specify it with retain and drop (see coeff.sel) or let this method select the highest possible number of harmonics.
