This package provides most of the popular indices for cluster validation ready to use for the outputs produced by functions coming from the same package. It also proposes to user the best clustering scheme from the different results obtained by varying all combinations of number of clusters, distance measures, and clustering methods.

It provides 30 indexes for determining the optimal number of clusters in a data set and offers the best clustering scheme from different results to the user.

Exceptionnal Network Motifs in biological networks
S. Robin, E. Birmele, G. Grasseau, M. Koskas, S. Schbath
NeMo package aims to extract motifs which are occur more
frequently than expected in random, in a given network. The
method used doesn't require any Monte-Carlo based simulations.
The number of motif occurences is compared (p-value
calculation) with well-suited count distribution (compound
Poisson distribution)

NeatMap is a package to create heatmap like plots in 2 and
3 dimensions, without the need for cluster analysis. Like the
heatmap, the plots created by NeatMap display both a
dimensionally reduced representation of the data as well as the
data itself. They are intended to be used in conjunction with
dimensional reduction techniques such as PCA.

Tools to generate Necklaces, Bracelets, Lyndon words and de Bruijn sequences. The generation relies on integer partitions and uses the 'KStatistics' package. Methods used in the package refers to E. Di Nardo and G. Guarino (2022) <arXiv:2208.06855>.
