scree

scree.PCA

scree.LDA

scree_min

scree_plot

A set of functions around PCA/LDA eigen/trace. <code>scree</code> calculates their proportion and cumulated proportion;
<code>scree_min</code> returns the minimal number of axis to use to retain a given proportion; <code>scree_plot</code> displays a screeplot.

The goal of 'Momocs' is to provide a complete, convenient,
reproducible and open-source toolkit for 2D morphometrics.
It includes most common 2D morphometrics approaches on outlines, open outlines,
configurations of landmarks, traditional morphometrics, and facilities for data preparation,
manipulation and visualization with a consistent grammar throughout.
It allows reproducible, complex morphometrics analyses and other morphometrics approaches
should be easy to plug in, or develop from, on top of this canvas.

scree function

<dl><dt>x</dt>
<dd>a PCA object</dd>
<dt>nax</dt>
<dd>numeric range of axes to consider.
All by default for <code>scree_min</code>, display until <code>0.99</code> for <code>scree_plot</code></dd>
<dt>prop</dt>
<dd>numeric how many axes are enough to gather this proportion of variance.
Default to 1, all axes are returned
defaut to 1: all axis are returned</dd></dl>
