plot.caps

This function creates a visualization of the result of the k-mean alignment
algorithm without returning the plot data as an object. The user can
choose to visualize either the amplitude information data in which case
original and aligned curves are shown or the phase information data in which
case the estimated warping functions are shown.

Implementations of the k-means, hierarchical agglomerative and
DBSCAN clustering methods for functional data which allows for jointly
aligning and clustering curves. It supports functional data defined on
one-dimensional domains but possibly evaluating in multivariate codomains.
It supports functional data defined in arrays but also via the 'fd' and
'funData' classes for functional data defined in the 'fda' and 'funData'
packages respectively. It currently supports shift, dilation and affine
warping functions for functional data defined on the real line and uses the
SRSF framework to handle boundary-preserving warping for functional data
defined on a specific interval. Main reference for the k-means algorithm:
