coeff_split

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

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

nb.h

<code>numeric</code>. Must be set to 2 for <code>rfourier</code> and
<code>tfourier</code> were used.


<code>coeff_split</code> returns a named list of coordinates from a vector of
harmonic coefficients. For instance, harmonic coefficients are arranged in
the <code>$coe</code> slot of <code>Coe</code>-objects in that way: $A_1, \dots,
A_n, B_1, \dots, B_n, C_1, \dots, C_n, D_1, \dots, D-n$ after an elliptical
Fourier analysis (see <a rd-options="" href="/link/efourier?package=Momocs&version=1.0.0" data-mini-rdoc="Momocs::efourier">efourier</a> and <a rd-options="" href="/link/efourier?package=Momocs&version=1.0.0" data-mini-rdoc="Momocs::efourier">efourier</a>) while $C_n
and D_n$ harmonic are absent for radii variation and tangent angle
approaches (see <a rd-options="" href="/link/rfourier?package=Momocs&version=1.0.0" data-mini-rdoc="Momocs::rfourier">rfourier</a> and <a rd-options="" href="/link/tfourier?package=Momocs&version=1.0.0" data-mini-rdoc="Momocs::tfourier">tfourier</a> respectively). This
function is used internally but might be of interest elwewhere.


A complete toolkit for morphometrics, from data extraction to multivariate analyses.
Most common 2D morphometrics approaches are included:
outlines, open outlines, configurations of landmarks, traditional morphometrics,
and facilities for data preparation, manipulation and visualization
with a consistent grammar throughout.
Momocs allows reproducible, complex morphometric analyses,
paves the way for a pure open-source workflow in R,
and other morphometrics approaches should be easy to plug in,
or develop from, on top of this canvas.
