coeff.sel

coeff.split

A <code>vector</code> of harmonic coefficients.

<code>numeric</code>. The number of harmonics to retain.

retain

<code>numeric</code>. The number of harmonics to drop

drop

<code>numeric</code>. The maximum harmonic rank.

nb.h

<code>numeric</code>. The number of coefficients per harmonic.

Harmonic coefficients are arranged in the <code>@coeff</code> slot of <code>Nef</code>-objects in that way:
$$A_1, \dots, A_n, B_1, \dots, B_n, C_1, \dots, C_n, D_1, \dots, D-n$$. <code>coeff.sel</code> helps to select a given number of harmonics and <code>coeff.split</code> returns a named list of coordinates.

Momocs is intended to ease and popularize shape analysis
        of outlines (especially using elliptical Fourier analysis). It
        mostly hinges on the functions developed in Morphometrics with
        R (Claude, 2008). From outline extraction of images and
        elliptical Fourier calculation to multivariate analysis and the
        visualization of transformations within the morphological
        space, Momocs provides a complete and convenient toolkit to
        specialists within every field that are, or may be, interested
        in morphological comparisons of outlines.
