%description
Implementation of the BRIk, FABRIk and FDEBRIk algorithms to initialise
k-means. These methods are intended for the clustering of multivariate and
functional data, respectively. They make use of the Modified Band Depth
and bootstrap to identify appropriate initial seeds for k-means, which are
proven to be better options than many techniques in the literature.
Torrente and Romo (2021) <doi:10.1007/s00357-020-09372-3> It makes use of
the functions kma and kma.similarity, from the archived package fdakma, by
Alice Parodi et al.
