%description
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 SRVF framework to handle boundary-preserving warping for functional
data defined on a specific interval. Main reference for the k-means
algorithm: Sangalli L.M., Secchi P., Vantini S., Vitelli V. (2010) "k-mean
alignment for curve clustering" <doi:10.1016/j.csda.2009.12.008>. Main
