a <code>list</code> of matrices of (x; y) coordinates,
or an array, an Ldk object.

(optionnal) a 2-columns <code>matrix</code> of 'links' between landmarks, mainly for plotting

links

(optionnal) a 3-columns <code>matrix</code> defining (if any) sliding landmarks

slidings

(optionnal) a <code>data.frame</code> of factors and/or numerics
specifying the grouping structure

In Momocs, <code>Ldk</code> classes objects are
lists of configurations of landmarks, with optionnal components,
on which generic methods such as plotting methods (e.g. <a rd-options="" href="/link/stack?package=Momocs&version=1.0.0" data-mini-rdoc="Momocs::stack">stack</a>)
and specific methods (e.g. todo-Procrustes can be applied.
 <code>Ldk</code> objects are primarily <code><a rd-options="" href="/link/Coo?package=Momocs&version=1.0.0" data-mini-rdoc="Momocs::Coo">Coo</a></code> objects.

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.
