plot.prcomp_qts

screeplot.prcomp_qts

This function creates a visualization of the results of the PCA applied on a
sample of QTS without returning the plot data as an object.

An implementation of statistical tools for the analysis
of rotation-valued time series and functional data. It relies on
pre-existing quaternion data structure provided by the 'Eigen' 'C++'
library.

plot.prcomp_qts function

<dl><dt>x</dt>
<dd>An object of class <code>prcomp_qts</code> as produced by the
<code>prcomp.qts_sample()</code> method.</dd>
<dt>what</dt>
<dd>A string specifying what kind of visualization the user wants to
perform. Choices are words starting with <code>PC</code> and ending with a PC number
(in which case the mean QTS is displayed along with its perturbations due
to the required PC) or <code>scores</code> (in which case individuals are projected on
the required plane). Defaults to <code>PC1</code>.</dd>
<dt>...</dt>
<dd>If <code>what = "PC?"</code>, the user can specify whether to plot the QTS in
the tangent space or in the original space by providing a boolean argument
<code>original_space</code> which defaults to <code>TRUE</code>. If <code>what = "scores"</code>, the user
can specify the plane onto which the individuals will be projected by
providing a length-2 integer vector argument <code>plane</code> which defaults to
<code>1:2</code>.</dd></dl>
